Oh, it's not THAT bad.
I would get Mario World too, if not for the fact that I got it as a part of a package deal with Super Mario 2 last year.
I've sort of learned that you should avoid buying 1st party Nintendo titles on VC BECAUSE they're far more likely to get offered up on these Club Nintendo promotions. If you look down the list, the games that have been offered so far include Majora's Mask, Link to the Past, Mario 64, Mario Tennis, Mario Golf, Mario RPG, Punchout, Dillon's Rolling Western Starship Defense, etc...
I know that sounds not-so-great, but in this meta-mini-game of predicting sales and discounts which the internet, and especially Steam, have indoctrinated so many of us into, its really hard not to think that way. I'm sure PS Plus subscribers do the same thing, with like "Well, there's no point in my buying the next Uncharted game because that will surely come up in PS Plus in 6 months.)
