GamingUnion.net: "In 2009, Capcom announced that they would be releasing Street Fighter IV, tossing the age old fighting title into the modern era of gaming. New moves, new graphics and new fighters would all come together to finally toss 3rd Strike out of EVO and fans couldn't have been happier.
"Then in 2010, they followed up with Super Street Fighter IV, an overall improvement upon the original which gained quite a bit of praise for its multiplayer integration and general bonuses to online play. The one thing you couldn't do, however, was play with anyone who owned SSFIV; buying this new version of the game was absolutely mandatory in order to keep up with any of the online updates, let alone any of the character rebalances.
"2011 would see the arrival of some new DLC for SSFIV and the release of another version of the game, Arcade Edition, which would come with some very similar sort of restrictions."
