[quote name='Roa']Remember that SFA3 was before SFII, then SFIV and SFIII.
Charlie is supposed to be dead since he was holding off Bison to let Guile escape. Chun-Li planted explosives on Shadaloo base and Charlie sacrificed himself.
Mike Haggar might have been running Metro City during SFA3. If they were to put him in SFIV, his moves would have been too similar to Zangief. Both of them taught each other the spinning piledriver and spinning lariat.[/quote]
Since when did Capcom's continuity matter though? They have so much retcon anyway. As far as spinning piledriver/lariat being redundant, that's irrelevant given the shoto moveset. I'd settle for those characters being added in with no story mode extras. Just highlighting Guile or Haggar, for example, and having a toggle button to swap between extra characters without requiring a new character select screen. Then they're in the game as bonus characters, not plot characters.
