I can't find SSBB casual, but the whole packpage is not going to be a trend, SSBB is great, it could get really hard and needs tons of time and efford to get all the things, most of the Fight games are just going to focus in the fight (1 vs 1 or 1 vs IA) and thats why I think they are keep fading away...
SBB introduced a strange fun factor, which I couldn't find in other fighting games (MK, KI, SF, KoF), and they just keep using it to expand the game...
Edit: Oh yeah the fun factor for me, is the chaos...
