Something I think needs to be addressed: Classic Mode and All-Star mode. I know that they can't change which Alternate Stage is selected, but what about the stages selected? In Brawl, it never chose Melee stages, only Brawl stages... But since Project M has so many stages taken over, moved, or whatnot, it's a little nonsensical, especially since characters like R.O.B would be on Fountain of Dreams, Mario would be on Dracula's Castle, it really makes no sense.
I would also like to see a version of Project M where you have to unlock all the characters, like downloadable from their website or Brawlvault or whatever.
It'd also be neat if they made it so that All-Star mode unlocks the costume trophy for each character (once/if each character has a costume), rather than the Final Smash.
Also, there's a coop event called "Where you at" where
Falco Fox and Captain Falcon has to kill a fox in three seconds. Memelopment Room.
I would also like to see more events like from Project M in reference to Melee events or popular Smash tropes... Such as a multiman Smash with Fox only on Final Destination and no items. Of course, that would also be extremely stupid.
Also it'd be neat if they could make it so that all metal battles take place in Metal Cavern.
Someone was talking about Ivy alts with mushrooms for flowers which I think sounds really cool. Parasect, Shroomiah and maybe Vileplume based colors would fit for team colors.
Huehuehue, that was me.
I even made crappy concept art for it, if you're interested!
