"Cryptic Studios had teamed with Marvel and Microsoft in what seemed a powerful alliance to develop the spiritual successor to City of Heroes but due to fierce competition in the MMO market and/or rumored disagreements between Marvel and Microsoft about licensing, the game was scrapped" (The game was cancelled years ago, so I am not violating the advertising rules)
yep. so for those who wanted a Marvel version of DCUO that was their story. they are the first ones who started a Superhero MMO but it didn't pushed thru.
