[Work in progress] A newbie guide to Fallen Enchantress.
So you bought Fallen Enchantress, or you got it because you're a War of Magic owner. Great, you got your hands on a Hell of a game!
You played the tutorial, liked what you saw, and decided to give the game a spin on a level advertised as 'fair', so you played a game on challenging. You did not pick Tarth, and you got crushed.
You restarted the game on "easy". The AIs dogpiled on you, and you got wiped out again.
Your ego will not allow you to play on the levels below "Easy", you do not feel that you have learned much from your two defeats, and you really do not know what you can do better.
So, what are you going to do, where are you going to get all the information you need? Not here. But I'll make a start.
First I'll make a disclaimer: these are my opinions. I did not design the game, my advice was no more followed in the Beta than anyone else, and it is not even clear that I am a good player, not without multyplayer.
Then I will try to explain a few concepts. This part is already more or less complete. Feel free to offer suggestions and point out errors.
Next, I'll point you to a very detailed play-through of a game on Expert difficulty (this is the highest sane difficulty) What makes it special amongst my dozen of play-throughs? The race is designed to have no obvious strengths of any kind, so all the tricks in that thread can be used with most races, vanilla or custom, on top of their specific strength. Some of the strategies that thread illustrates are: snaking, designing early troops with specific upgrades in mind, rejuvenation, diplomatic victory, dominion push, warhorses, creative terraforming, etc...
Finally, here is a link to what is the single most overwhelmingly powerful design I know of. How powerful? I've taken it to a trivially easy victory on Insane difficulty. I do not expect the design to remain valid for long. It works as of v1.02.
There is even something more powerful - the stealth (link not here yet) race trait, which Tarth has by default, and which any custom race can get. I recommend against using it, because it really takes two thirds of the game away, and no only does not allow you to experience many of the thrills that Fallen Enchantress offers, but also teaches you bad habits that will make your game very hard without stealth.
