http://www.smashbros.com/en_us/index.html Just revealed that demos for VC games will be on the disc, and they seem to be done in the same method the Genesis games were done on Sonic Gems Collection. Sort of crappy that we don't get the full games nor does it seem like Nintendo will do a demo feature for the VC, but I can totally see hacks and codes for it once a Action Replay comes out for the Wii.
This is a cool bonus... IT IS nice for those people who haven't played these games at all or in a long time. I can imagine people complaining because they're not the full versions. Meh. I am buying the game for Brawl -- little stuff like this is just a nice gashopon on the side.
I think asking for full version would a be a bit much. This game is already giving way more for you buck then most $60 games do.
