It kinda hit me today when I was looking at the GC million sellers list.

 The 2 best selling gamecube games have not had Wii Versions Yet...

MK:DD  &  SSBB

I mean look what Mario has done for the Wii. It  singlehandedly is FORCING all Core gamers to get a Wii to play it(unless they are Platformer haters)

MK series has be in the top 2 on every console since the SNES, and I don't think the Wii will be any different(ok... not counting Wii sport and WiiFit)

SSBB- The cube version sold 6.6 million on just 23 million consoles.... Imagine what it can do on a userbase the size of the Wii's.   I personally believe 20mil LTD. is not out of reach (it would be the first non-pokemon, non- bundled game to do so)

I see MK doing 10mil PLUS. It did 6.62 on GC and almost 10 mil on 64 and the Wii userbase will be at least 70 mil(super conservative) when all is said and done.

I also like what I am hearing about new IP's, I just hope the core gamers jump over to buy the Great new IP's because the casuals don't like new IP's to much. (see Zack and Wiki)

There are several reasons the afforementioned games sold that well on Gamecube:

1. Lack of other quality games
2. Lack of adequate quantity of games
3. SSB was a Gamecube launch game
4. Gamecube install base was more "hardcore" than the Wii
5. Gamecube's attach rate is way better than the Wii

Also :

1. Final Fantasies sold better on PS1 than the much bigger userbase PS2
2. Zelda Ocarina of Time sold way better on N64 than Twilight princess on Wii & Gamecube

Install base isn't everything although I believe that both games will eventually sell better than their Gamecube counterparts.

We all know this, both the wii and playstation consoles will have amazing games next year. Im sort of dissapointed on the 360's line up, I hope microsoft announces good games for next year.

@rout
I am pretty sure that FFX sold better than 8 and 9, and maybe 7
12 was like 9, released late in the life cycles. The PS2 and PSX were with 15-20% of each other. in fact the reason the PS2 has blown by the PSX so much is its 7 year life span.

SMG will sell much better on Wii, it is alread 60% of SMS. Also MK dominated the SNES, which IMHO had the best library EVER. I basing Smash off the hype and the fact it will bring many core gamers over. SSBM was not a launch game. close to it, but not a launch.

 Way better?  Depending on when the new Wii Zelda comes out, it is possible for TP to have total sales within 1 million of O of T.  I doubt TP can catch O of T but it may be possible.

Sorry for all the posts, my browser got stuck...

Hey, you forgot Final Fantasy 11.
