Since this is an engine test I will not go into gameplay issues except to say that even with all the limitiations this looks like it has a LOT of potential. I played the single map available with all three demigods at various settings and found no bugs outside of those listed in Frogboys post. Actually the only one I really noticed was the missing icon when certain skills go active in the F1 slot. Kudos Stardock!
My best settings for smooth graphics are 1280x800 with no anti-aliasing, low shadows, medium textures, all other video settings high and it's pretty good- bumping it up any further than 1440x900 really hits the framerate hard.
The game runs great on my work laptop and I would just like to thank Stardock for a nice surprise- most beta's I have tried were not even close to this playable/fun.
I'll try different settings to see if I can break it for you- looking forward to any further development!
