I find it a little bit funny that fighting games are the one genre where everybody hates expansion packs.
It's a little different than an expansion pack. Both SSFIV and Ultimate MvC3 are retail games. Sure, they carried a reduced price tag at launch, but they still essentially forced fans to re-purchase the game they already had in order to get the new stuff. Capcom has been perpetuating this practice with Street Fighter since the early 90s so it's no big shock, but many fans think this is ONE area where the DLC era should benefit them.
