OK, I think I need to step in and say a few things. I kind of agree and disagree with all of you.
First of all, Killa of PS2, I thought Wario World was great. It and Wario Land VB I think were the best Wario games made, and I think Wario is one of the best Mario characters. There's a lot of reasons, too many to post here. However, I did like the gameboy Wario games a lot. One way to look at it is that you can't really compare Wario Land and Wario World, as they're completely different.
Second off, Lonic, you're right - Wario rules. However, Birdo's right that Lanky is not a Mario character. You say that Lanky is a DKC character, but he isn't really that either - he was never in any of the DKC or DKL games. I personally would classify him as a "Rare character." Everything else you said is right, though.
Third, Birdo, you're right about Lanky, as I just said. The only thing I disagree with you on is your statement on Bowser. Sure, he's an evil guy and all, but you've gotta admit that he's darn cool. In fact, I think that his evilness makes him even cooler --- but that's just me.
I mean what I mean, but if you know what I mean, how can you mean what I mean - y'know what I mean?
