I want the Wii version for the controls, yes, extra characters, yes. And also:
The thing I am online with is a laptop, a shitty one that is. I don't lag Minesweeper though. But it starts to lag on ANYTHING when it's powered above 3 to 4 hours. So what I am saying is I couldn't play SMB on a weekend session for longer then around 3 hours.
The only thing I got else is the Wii.
Also there is the thing of playing SMB while having the computer running and be chatting and stuff.
My Laptop will lag if I have any program open besides the game.
So if I only run that game and nothing else, it will lag after 3 hours.
I am very limited with that, you see?
Also it's just preference, I have all those oldschool games downloaded on the Wii and you know, havin' an evenin' playin' with friends, chillin' in front of the Wii (on a big TV screen btw and not my tiny laptop screen (another reason for Wii version)) you wanna play some games and then you go "you played super Meat Boy yet?" and they go "oooooooooooooooohhhhhhhh!!" and then you get your laptop.............
So yeah, I would have to buy a controller too or get fancy with the program someone posted above and get my Wiimote running on my PC without real knowledge in doing things like that.
