GTAIV by a lot. I can't believe some people honestly think SSBB will sell more, LOL.
The last time you said this, I suggested a bet for lifetime sales and you backed out. Also, if you would have that much faith in GTAIV, you would have been willing to bet SSBB vs. GTAIV 360 version only. But you even rejected SSBB vs. both versions.
You were also laughing that people were saying that Super Mario Galaxy would manage to have higher lifetime sales than Halo 3. You were calling Galaxy a flop after first week sales, you created at least two troll topics to bash Galaxy. But how do you think now about the idea that Galaxy will beat Halo 3? Galaxy is showing enormous legs, while Halo 3 is mostly living off of its big opening week. Galaxy will eventually overtake Halo 3.
GTAIV vs. Brawl will be similar. GTAIV will have bigger first week sales, but SSBB will have the much better legs, eventually overtaking the combined sales of both GTAIV versions. Why am I so sure about this? Because the videogames market is currently making a transition and will soon become synonymous with Nintendo again. Nintendo's franchises will reclaim enormous popularity and sell ridiculous amounts of copies. And what's SSBB? A compilation of Nintendo's biggest franchises, a game with characters recognized by pretty much everyone. This game is going to sell for a very long time.
The bet: SSBB lifetime sales will be higher than the lifetime sales of GTAIV for 360 and PS3 combined. The loser will be banned for a month and will have to keep the outcome of this bet in his signature forever.
After at most two years of both games being on the market it should be possible to draw a clear conclusion which of the games is going to end up with higher lifetime sales. So once it can be said for certain which game is going to sell more in the end, the bet comes due.
