DC Universe Online was great and all, but forcing players to define their own hero rather than play as one of the iconic characters was a little disappointing. Looking at the number of copycat heroes pretending to be Batman or Superman players made, it’s clear that people want to play the heroes they read and not some washed-out knock-off.

Marvel Heroes (originally called Marvel Universe Online) was the first licensed MMO to let you take on the role of a unique hero and enjoy all of their powers. Though it never came out, the beta showed so much promise, allowing players to take a whack of characters for a spin including the popular ones like Captain America, Spider-Man, Iron Man, and Hulk, and a few lesser-known protectors like Rocket Raccoon and Squirrel Girl.
