[quote name='rapsodist']The biggest difference is that all those games you listed (with the small exception of LBP's 18 user-created levels) have extra content that can be bought as DLC. Super SFIV doesn't. I know, I know, someone will tell me the way everything's been reworked means that there couldn't have been a simple DLC add-on or a firmware fix...[/QUOTE]
I'm going to do just that:lol:...
Well... this deals with software. For DLC to work, it has to be planned prior to release. I don't know if Capcom did that or not. If you want a game that more efficiently uses the system's resources, then a newly compiled software is better.
Alternatively, if they did plan for DLC for every single aspect of the game (e.g. - the timing and types of moves, as well as animation data), then all of those information will have to be read and interpreted each time the game is loaded. This implies at the very least, increased load time.
I'm not exactly happy that they took this route, but considering the alternative, I don't exactly blame them either once I've thought about it.
