characters dlc are a good thing since you caan update the game without the need of buying a new disc the next year, in fact so far the only companies that have made dlc chars the way that i like are Arcsys with BB and NetherRealm with MK, and more likely Revergelabs with Skullgirls when they start releasing the characters as dlc; capcom only did it right with SSF4AE, but with mvc3 and now sfxt, it seems that they are not aware what is the whole idea of dlc chars
its about expanding the game, updating it, to release the revision as a patch and not a new disc
not to release a game with a good portion of it locked and then release the unlock files like 5 or 6 months after
