I love diablo style games but there is nothing amazing about orc: vengeance. However that's not to say it's a bad game. It's just very straight forward and doesn't offer anything new. If the game was $0.99 I think it would be well worth the price but for it's $2.99 price tag... it's not worth it personally. Still, it's probably the best RPG I've played on the iOS, so if you are a die hard diablo fan, go grab this game.
My interpreted value: $0.99
