Have we really become so polarized in the gaming world that we cannot enjoy multiple titles at the same time? I personally support all of the following games...for the simple reason that ARPGs are very hard to make. They really are complex from a design standpoint, and only the best of the best should attempt to make one, which is why we rarely see them.
But NOW we are in the golden age of the genre, with at least four titles this year alone. We should be jumping for joy at getting new adventures to enjoy, instead of ripping them all down because of blind-fanboyism.
D3 Pros - carefully crafted experience for the players, deep itemization systems and excellent art design.
D3 Cons - Always online, less randomization, RMAH woes, removed most RPG elements
TL2 Pros - offline play, modding (Steam workshop confirmed!), $20 for a AAA title, created by original Diablo 1&2 designers, and the itemization is spectacular (played the beta...truly awesome gameplay, folks), pets, fishing
TL2 Cons - cartoony, like WoW, unlikely to have a ton a post-release content added
BL2 Pros - Guns guns guns, excellent art style, FPS mayhem
BL2 Cons - Less story-driven, not as compelling as a fantasy world, high price point
PoE Pros - slick skill system design, strong emphasis on individuality, great indie-development team, dark gothic feel, free to play
PoE Cons - Storyline is secondary, passive skill system is overly convoluted, far more grinding required than others in the market.
The whole point of this post is to get people to stop drawing lines in the sand when it comes to those types of games. Each has its pluses and minuses. Each has a specific element to them that makes them stand out from the competition, and all are valid options for your ARPG fix.
Now that I have played Diablo 3 to death, I am ready for a new adventure, and I will be playing all of these upcoming games.
If you like the genre, stop being jerks for the sake of being jerks, and support them ALL!
