Illgresi

There's no actual plot in Illgresi and all you have to do is to conquer the enemies by destroying their bases as well as all their units.
As soon as the game starts, you will have a few units under your control and the possibility to train new ones from your home base. In order to win you will have to follow a few essential steps that will have a big impact on how you approach each battle.
To be able to recruit more units and gain resources faster, you will need to capture as many bases as possible before your enemy does. Capturing bases will increase your income, giving you the possibility to recruit units whenever your army needs them.
Each captured base has three upgrade tiers with the last one allowing you to spawn units from there instead of your main base.

The Triangle of Death is the key to success

In Illgresi you will have only three possible units to recruit: goats, witches, and archers. Each of these units has its strengths and weaknesses when fighting other units and this can be simply shown in a simple diagram called the Triangle of Death.
For example, goats are stronger against archers and weaker against witches, archers are stronger against witches and weaker against goats, and witches are stronger against goats and weaker against archers.
Keeping that in mind when spawning new units and leading them into battle might help you win each encounter while focusing on a single type of unit will surely lead to your defeat in the long run.
Illgresi is probably the easiest to learn RTS due to its simple rules and limited unit types but that doesn't make it less fun at all. For the moment there's only one playable map although, I'm pretty sure more will come if the game gains a little bit more notoriety among players.
