Ok right up front, I have to say this game is superbly done, at least by first impressions... Sadly enough I won't be playing it in spite of the fact that i really enjoyed it for many hours, due to its extremely strong demonic elements and occult nature. I say that up front as a disclaimer, but also as a warning to those that might be offended by this type of content. if you have any problems with actually summoning demons (not pets) in games or overtly occult abilities and magic in a real-world (albeit fictional) environment, don't try this game.
TBH, I wish that they could make a game with the great game mechanics of this one without the occult overture. I would be all over that one. Nuff said.
