Demigod is a great game, don't believe the low reviews
The pros:
-The visuals and audio are fantastic
-The demigods all feel distinct, and are all satisfying to play with
-Plenty of different battlegrounds to choose from
-Plenty of RPG-like trappings that keep game-play dynamic and very re-playable
-Despite the lack of a tutorial or story-driven campaign, playing offline against A.I. opponents for an extended time will teach you tactics and the fundamentals needed to play online against other players
The cons:
-No tutorial for players not familiar with this type of game
-Initial online stability issues on launch
-Demigods possibly need balancing updates
