I've played non-stop for hours. The game is fun. At times it ALMOST felt like playing MoM (almost!). Kinda liked the deja-vu feeling! Needless to say, this is VERY promising.
However, there are issues, of course. For the moment I'll avoid commenting on content, balance and so on as I'm still not familiar enough with the game. It's too early, really: we all need to play a few games to understand what works in the long run and what doesn't.
So I'll just report my technical issues: a few crashes (nothing unbearable, already e-mailed to support), but, sadly, SEVERE performance issues. I mean, the game really slows to a CRAWL, and becomes almost unresponsive as the game progresses. My machine is fairly powerful (quadcore 3.4 Ghz), so I'm inclined to believe it's a software problem. Anyone had similar issues?
Anyway, outstanding "first step", looking forward to have the final product installed (and possibly modded)
