I can't believe how many resources they're sinking in to this to what amounts to a single player campaign with a bolted on survive the waves of enemies online coop mode
I'm not sure they're going to 1) sell enough costumes to 2) fund more single player story content to 3) keep user engagement to 4) sell more costumes
When people realise you can't play this "ongoing" story with your friends it's probably going to die on its arse
Avenger's doesn't really work as a game concept (as much as I'd like it to) because of how diverse the character/game mechanics need to be. You either end up with a bunch of characters that do similar things or you have a very basic move set for each one so you can incorporate different but very basic character traits (LEGO Marvel)
The game looks better than it did but the graphics and style aren't even the biggest problem for me, I just can't see how this concept is going to work. I'll try the beta and hopefully I will be wrong.
