You start with a town (Fort and the Centaur Stables with a Tavern included), and with one hero. What do you do?
Day 1, Week 1, Month 1.
Enter the city of Rampart, and buy a second hero. She/he is preferably also from Rampart. If there are two Rampart heroes in the Tavern, choose one by either their speciality (a very useful one in the beginning of the game is the +350 gold), or by their army - you will need Elves to fight through shooters' guard, if there is any.
Buy everything from the city.
Now, combine the armies of the two heroes, and give it all to your main hero. Leave the Rampart.
You first need to find your Sawmill - it shouldn't be very far away from the main town. Give this task to your main hero (since he/she has all the army), and go to the direction where you think the Sawmill is.
Your 2nd hero is still in the town - enter the city again, and then the Village Hall. Build the Town Hall - you need money, and take your 2nd hero out.
If it is possible, lead your 2nd hero in the parallel way from the main hero. With him/her, try to find the Ore mine, which is almost as important as the Sawmill.
If you will find some chests by some or all of the heroes, leave them in place, or take only a few for money purposes, but only if necessary. You will need these chests later - you will gve them all to your Guardian of the Main Town hero.
BUT: If your already hired 2nd hero is a good one, you can give him/her these chests, not waiting for anything.
Any resources that you find, collect them; if your Sawmill is guarded by a weak unit, kill it; if you will find a good artifact, take it.
After your heroes are tired and can't go any farther, after your town is built, rest.
If you still didn't find your Sawmill, find it now and quickly.
Any Rampart creature generators around - flag them, or at least those that do not involve fighting with the guardians (look for the Dragon Cliffs - you may be lucky enough to find the place of residence of the great Green Dragons themselves!). Also, flag any mines around that you can handle - the sooner you will start to stockpile your resources, the better.
Do not buy a 3rd hero unless she/her isn't very good, or if you desperately need him/her for exploration purposes.
Build the Homestead.
Build the Dendroid Arches.
Your two heroes can explore around till the 1st Day of the 2nd Week.
Build the Mage Guild level 1.
Build the Marketplace.
Build the Dwarves.
Build the Citadel.
Day 1, Week 2.
Run with your remaining army and heroes back to the main town - you'll be doing army shopping!
Enter the town, and build the Upg. Homestead. Then, upgrade any Elves that you have (if you have any at all), and look inside the Citadel.
But first the Grand Elves, then the Centaurs, and the last - the Dwarves. If your hero does not have a Spell Book, buy it now.
Wait for a day - don't leave the city.
Check your tavern - always do this in the beginning of the week. Just don't buy anyone unless it's a great hero.
Now, upgrade the Dendroid Guards into Dendroid Soldiers, and buy them.
You are now ready to leave your hometown! Go, and begin collecting resources - enter Crypts, Dwarven Treasuries (be careful in these, though...), free the creatures' dwellings, and most importantly, flag all your mines that are in your territory.
Build the Blacksmith.
Continue exploring your territory till the 3rd week.
Build the City Hall.
You should have a lot of resources, so build the Castle.
If you can already build the Capitol, build it, but if not, don't worry and build the Enchanted Spring.
Build the Capitol, and wave with the flag of your Kingdom to the rest of the world! :-)
Day 1, Week 3.
You should have already conquered all mines around your town and territory. If not, finish doing so and return back to the town.
Build the Battle Dwarves.
Build the Centaur Captains.
Return to your town, and wait for two days - gather money.
Buy everything you have, and construct the Dendroid Saplings.
Leave your town once again, and this time, with a big army. Head towards anything that you haven't captured yet.
BUT: DO NOT enter the Naga Banks or the Cyclopses' Stockpiles. The same applies for Dragon Utopias, if you have any near you.
The thing is that you will be dead in a second with an army that you have now, and will not even be able to say "mama" once. Of course, this is a bit too much - you might be lucky enough to meet 16 Nagas without the Queen, than the 50 Nagas with the 10 Queens. But I warned you!
Build the Miner's Guild.
While on your adventure, look and enter any Magical shrines which will give you free spells from the 1st level till the 3rd level. Also, look for the Universities to learn the skills that you need, and the Libraries of Enlightment to raise your primary statistics by 2. As well as that, enter such structures that raise your primary statistics by 1 or higher, such as the Star Axis (+1 Spell Power), or the Arena (+2 Defense or Attack).
If you will find a Refugee Camp a long way from your home town, buy a hero and send him/her to collect good creatures from it (who knows, you might get a Azure Dragon!), and also to collect any resources from the territory around it.
Unicorn Glade - build it now!
If you have money, and a lot of it - you can build the Dwarven Treasury if you might like, it is the 7th day and you will get +10% tomorrow of all your money. But you can also wait, if you like.
Day 1, Week 4.
You have already a little mighty empire - there is not much doubt that you have already found and conquered a second town.
But your army must be getting smaller, and you need reinforcements. You probably can't buy your whole army from the town - your Guardian Hero (you do have one, don't you?), will simply not have anything to protect the town with.
So, buy a new hero, and give him half the army that you have in that town, and lead him/her to a meeting with the main hero.
After they meet, don't dismiss the carrier - he/she can be a explorer in front of the main hero - to take unwanted events up, for example, or to just simply uncover the territory.
Never walk around with "Quick Combat" on! It might happen so that your hero-explorer will be under attack, and on "Quick", he/she will just be killed, and you won't get a chance to look at the enemy's army.
Build the Resource Silo.
Now, you need to build the Dragon Cliffs, and upgrade the rest of your army, right? To build the Dragon Cliffs, you need to have the 2nd Mage Guild ready.
Enter the town, and build the wanted structure. Since you already have the Resource Silo working for you on Crystals, it is only a matter of time before you will build the Dragon Cliffs.
Supposedly, you already have enough Crystals to build the Dragon Cliffs. This rarely happens, but it does. If you do, build them, but if not, you can either sell something at your Marketplace for the Crystals, wait a few days, or try to find some on the map.
This is the last week to build the Dragon Cliffs, so remember that!
This is the LAST DAY to build the Dragon Cliffs. Do everything in your power to build them - probably, most of the other opponents' towns already build their 7th level, except maybe the Dungeon and Castle.
Also, remember to save your game before sleeping - it is usual that a Plague happens in exactly Month 2, Week 1, Day 1. So be careful.
Month 2, Week 1, Day 1.
You are all built up - except the Mage Guild and the Upgrades.
Today, build the Upg. Enchanted Spring - these Silver Pegasi are useful, but cost a lot. But you still need them upgraded...
Build the Upg. Unicorn Glade. Soon, you will be able to purchase Dragons, but you need them upgraded, and that costs a lot as well. So, you need to wait.
Build the Mage Guild level 3. As you might have noticed, you need it to upgrade the Green Dragons into Gold.
As you might have noticed again, you will not have enough Crystals to upgrade the Dragons after so recent a constructure of the same beings.
So, you need to wait again. Specifically, you need to upgrade the Dragons the last day of this week - the 7th day.
But now, you won't be able to build anything at all - you need money, ore and Crystals to upgrade. And the only things that you haven't built except the Gold Dragons are the Mage Guild and the Mystic Pond.
Since you are NOT going to build the Mystic Pond in the game at all, and won't build the 4th level Mage Guild now, you ca only wait till the 7th day.
There is a very big chance that you will be attacked on the 2nd month. So, upgrade the Green Dragons now - the more troops you have, the better.
Now all that's left for you to build is the Mage Guild.
But - you decide for yourself when to build it. It is for you to decide when to build the 4th and 5th levels - either when the opponent attacks you, or when you will need the 4th level spells yourself. Or maybe you just need to build it some other time? As I said, you decide that.
