I had quite a bit of fun on the demo, but most likely I'll wait for a sale on this. I'll purchase it for around $20, but not $50.
I feel like I've easily gotten my $50 worth if not more myself but YMMV as always.
The thing is just drop dead gorgeous as well even if you're not using highest possible eye candy settings. Scales great but if wow, if you can max out all the eye candy you're really in for a treat.
Great game!
