Yep, the so-called reviewers are all hyped up waiting for Diab-blow 3 which will be just another clone of all the other games Blizzard does, thus you get bad reviews by bad reviewers, who are do not like change or anything new in their small minded view of RPG's!
Oh well, I have also waited until a game price dropped to buy a game, only to find while I was waiting to save money because some bad review worried me, thousands of others were loving the game!
Always try the demos of games, and check the game developers forums to see what the "real" gamers like or dislike about a game instead of reading reviews made by someone who is getting paid to play games and may have a grudge against the developer or publishers of previous games.
Like myself... glad to see your enjoying this great game!
