great ideas guys, especially spak with the items and pikachu evolving thing; i'd love to see that.
even a few smaller things would make me happy; for instance i never liked the food items in Mellee, they felt really out of place. they should just have items from the games themselves instead of those 'real world' items. they should be themed.
a mushroom from mario wouldnt work becuase they already have those, but say a small heart from the LoZ to take 5% off your damage counter. the different energy capsules from metriod, a hamburger DX from EB, things like that. that way you can keep the Nintendo-verse feel without breaking it because you see rice balls and ice cream cones on the battle field. each item would take off more damge from your mete, the heart container being the ultimate...that is unless there was a 1-up mushroom (stock matches only) that appeared VERY rarely and would add 1 more life to your character. and you thought scrambling for the heart container and super star were crazy...
a more interactive EB level would be cool too. fourside kinda blew in Mellee, they should of had Cute lil UFO's attacking you randomly. they wouldnt be very strong but they could shoot down a beam that would stun you in place for a second, giving another player an advantage to SMASH you off the stage. or Crested Bookas breathing fire on you or something.
a new metroid stage could have space pirate attacks, or random releases of metroids. if you don't destroy it they get bigger with the energy syphoned from each character. i like stages like that, with lots of interaction. i just dont want to see ALL stages like that. sometimes you just need a plain level (final destination) to lay the smack down on your mofo friends
