After playing Fallen Enchantress (FE) for more than 20 hours, I feel that Stardock got a gem on their hands but with some rough edges. In particular with regards to game stability.
Memory leaks that result in "out of memory" crashes are frequent - and guaranteed with a couple of reloads on a saved game that has progressed past turn 150 or so.
Another problem are the apparently random game freezes which occur right after clicking "next turn". I've seen them both in the early and the late game but they do appear to be more frequent towards the late game. The music keeps playing and the mouse pointer turns into an hourglass but nothing else happens until Windows decides the game isn't responding anymore and terminates it.
These problems can be somewhat circumvented using auto save and by only loading a saved game right after starting FE but are still very annoying so here's to a quick stability patch to an otherwise excellent game.
