It's always a sad day when a game disappears; alas, that day has come for Marvel vs. Capcom Origins.
Capcom's 2012 fighter, which bundles Marvel Super Heroes and the original Marvel vs. Capcom, will be vanishing from the PlayStation Network and Xbox Live stores this month. The game is being removed from PSN rather soon, as December 23rd marks the game's removal. That means PlayStation owners have to pick it up tomorrow. Xbox Live loses the game on December 31st, so there's a few more days to get the money together if one needs to.
There has been no reason given for the removal; however, it's likely a recent license expiration is the cause of the loss.
