I'm really enjoying this game as well (just started playing the beta this weekend and could not put it down).
Menus, UI, Graphics, VO/personalities of the heroes, abilities, play style, pacing all feels really well done. You're leveling up and upgrading your gear constantly along with smashing face.
Inspired = Has some elements of but not exactly the same game. Ripped off = Exactly the same game, typically with a different face lift.
I believe *inspired by* is the correct term to be used.
O' and seeing how they've listed the DEMO to be TBD, it's a good bet that there WILL BE A DEMO. Getting a DEMO and finishing up a game at the same time in most cases is not a realistic!!! It's call finish the game first, then make a demo.
I believe the point the other poster is getting at is with GPG's Supcom is that it was released before it was really ready and the game did not get really good until the xpack. To that point I agree, it's not that they don't support there games it's that the last one need a little more love before it should have gone out the door.
Demigod looks seems like it's been given quite a bit of love and I like how Stardock operates, I have faith that this match up has produced a great game that will be supported after release.
