If you think Olimar is boring and useless you haven't been watching the right gameplay videos:

If you want more of Olimar kicking ass, let me know, cause I've got plenty... Olimar is only good in the hands of a good player, but he is hardly useless.  You need to be smart to use Olimar well.

still looks pretty lame...
but that yoshi's island stage...wow, so purty. now I want a yoshi platformer for wii.

got any nice videos of wario? I haven't really seen much of him.

That may be the first full video of Yoshi's Island I've seen.

I wish people would play on more than Final Destination, Battlefield and Smashville. BORING.

I want to see more of Port Town, New Pork City, Delfino Island, as well as the Donkey Kong stage. Also, I have never seen Rumble Falls in action either. Oh, and the Metroid Prime stage. Damn...where are these stages in video form? I wish people would play them more.  I'm sure Rumble Falls sucks...but I would like to see it suck in action hehe.

Yoshi's Island is definitely my favorite stage to play on, and same goes for my friends.

Wario:

lol, thanks naz. you're like a living smash bros encyclopedia.

Wario's Fart is really interesting.

If you go around 2 minutes with out using it, it charges up to the max; pretty sure it works even if you die.

Also, if you eat items, it will charge up faster.

eat items? explain.

also, wario looks better than I expected him to be. surprisingly quick too.

Wario can eat items. Wasn't this explained in detail on smashbros.com? I'll try to find the page.

 EDIT: Hmm I can't find anything on it, but I know he can eat any item. The more you eat the stronger his farts are. A fast way to do it is bring out his bike and eat it, and then bring out another one and eat it, etc.

Hahaha...taking out a bike, breaking it, and eating it...repeatedly...to build up a massive fart is something only Nintendo could think of.
