His own game? No. He hasn't had enough time in any game yet for him to have his own character-defining title. It'd be like making Super Birdo World or New Super Mouser Bros. However, his own spot in one of the platformers or RPGs I think would be great and would then open the doorway for his own exclusive title.
...oh wait, all i know is that he's Wario's brother.
There doesn't seem to be any abilities that he has. And it would be repetitive just to have him playing as Mario (Or Wario, for that matter), and there doesn't seem to be any story behind him (Examples of what i mean:
Mario-Plumber that saves Princess Peach from Bowser
Luigi-Mario's brother that pretty much follows Mario
Wario-Treasure hunter/lover/what ever he is involved with treasure
Looks like Capitan Hook;
walks like an idiot;
his jump is awkward;
he's too large and too tall;
he's thin and weak...
Probably the reason whereby Nintendo didn't make any game with him as main character. Maybe they'll do Wario as main character, and Waluigi as second playable character, but no one will have fun playing with someone like Waluigi (:/
I think there'd be a lot of potential to put Wario and Waluigi in an RPG similar to the Mario and Luigi series, but if I recall, Miyamoto and a lot of people at Nintendo aren't too fond of him, and see him just as a filler for sports games and whatnot. Dunno, even though I'm not a huge fan of Waluigi, the RPG games have generally done a great job of expanding even Mario characters, (i.e. Bowser in BiS) so I wouldn't mind seeing it happen.
Hmm.. It could happen, but I don't see Waluigi as side-scroller material. Basing off of Mario Party 3's "Waluigi Island" I think it's safe to say that waluigi can build and/or invent stuff. therefore it could end up as a Puzzle game or something, which I don't think many would be fond of.
Nintendo really needs to expand Waluigi's character first before trying to make a game offa him. Like ST said, they could throw him in an RPG with wario or something.
Waluigi isn't even Nintendo's own creation.
I wouldn't exactly want to play a game where you play as Waluigi. It's just not going happen...
Waluigi was just made as a doubles partner for Wario so that Mario Tennis on Nintendo 64 could happen.

Bowser's Attack On Yoshi's Island Is Canceled...
I'll be away from the 24th of July for a about a week.
I'd like to see a game starring Waluigi, but I don't think he's popular enough to have his own title, since people would rather buy a game featuring a familiar character than a game featuring some random purple guy.
