I was simply pointing out that while Home may be the most downloaded and most played PS3 exclusive, it's not the best-selling, because nobody's bought it.

Out of what's known now?

1. Gran Turismo 5
2. Gran Turismo 5 Prologue
3. LittleBig Planet (+GOTY Edition)
4. Metal Gear Solid 4: Guns of the Patriots
5. God of War III


...Agent won't be that big and it won't stay exclusive (1 year window at best). Ditto for Versus.

I don't want GT6 to come out this gen.

And even though Yamauchi said that, I still don't think GT6 will come this gen.

I think you have to put those numbers into context. You are just looking at them out of context. GOW was a new IP that generation and it didn't come out until the console's 5th year. That is a long time into a consoles life cycle to be introduced to the user base. Also GOW II was released after the PS2 had started to decline and after the PS3 was already released. Just compare GOWII's sales figures to any PS2 game that came out around that time. GOWII kills them. Also you have to think about the reception that the GOW collection is getting on the PS3. It is selling pretty well for a remake collection. The reason why it was even released because they know a lot more people are interested in the GOW series than have actually played the first two.

GOWIII will sell very well. It has critical acclaim(winning many GOTY awards for both iterations), it has an established brand name now, it will have Sony's marketing behind it and it has the hype and momentum of the Playstation community, and it's target demographic is the same as many of the top selling HD console games(GTAIV, MW2, MGS4) unlike in 2007 when many of the PS2 sales had become for more casual/kiddy/immature gamers while it's core target market had already moved on to the 360/PS3 or was at least focused on moving to it rather than purchasing more PS2 games. 

GT5 Prologue is trailing Metal Gear Solid 4 by over half a million units, plus it isn't getting any marketing support, so it won't go ahead of MGS4. Little Big Planet? The game, while being marketed and a GOTY edition came out recently, is trailing MGS4 by over one and a half million units, so I don't think that will pull past Metal Gear Solid 4 either. I'd put Uncharted 2 on the list as well. 

There could be some Wii sports type game that releases early for the wand and is sold for cheap and it will become the PS's top selling exclusive. Other than that I don't see how anything can top GT5 or even come close.
Had U2:Amongst Thieves had a really good multiplayer then I would think it would sell a lot more and if U3 can have a great multiplayer it will sell around 6 or 7 mill but because third person shooters tend to not be nearly as popular or as fun/good as fps I don't think Uncharted will ever get passed that threshold of every single person has to own a copy. As is every single person just has to PLAY the game. And my copy is more than enough to satisfy me and my friends.

I beg to god that doesn't happen.

Don't you think Uncharted 3 would be on there somewhere? Or is that too far in the future to be considered for hte chart?
