This is a nice game. I have had so much trouble with NWN2 I got from the MacUpdate software package, I wanted to try this. It is truly turn based. You have a chance to setup each attack with each character in your party. The game play map is huge: looks like I'll have fun with this for some time.
I'm using 10.7 Lion and it has been running perfectly.
Definitely worth the $20. Thanks Spiderweb Software!!
