Better than I expected.
I'm going to come out and admit it, I pirated the game. Due to the fact that there was no demo and reviews have been less than stellar, citing all the technical problems. I still held out hope for the game and wanted to try out some singleplayer.
I've gotta say, I'm really blown away by the game. Graphics are awesome, arena's are all well designed, Demigod's look awesome and their all unique with their playstyles awesome customization through abilities and items. I'll definitely be picking up the retail if I can find any in town.
I've been practicing with singleplayer and even though there's no tutorial what-so-ever I've gotten the hang of some of the Demigods but I really want to take what I've learned online and see how I fare against all the DotA vet's. I never tried DotA but I hear Demigod is pretty similar.
Considering that the game is essentially multiplayer only and that a Serial key is only required for online play, I'd say that Stardock/GPG should market the game as a free digital download so anyone can download and try out some singleplayer Skirmish's and charge the $39.99 for the multiplayer serial key. My 2 cents.
