Assassin's Creed was a system seller ?

FF Versus XIII might just be, as someone suggested. It's exclusive, pretty high-profile and most likely good.

I'd say LBP has a good chance although I wouldn't be so sure about it.

MAG has a chance but at the moment it's pretty hard to say. I'm afraid they're not going to hype it enough to make it a system-seller.

I really think we're mostly moving away from system-sellers. All consoles have some AAA games and after they have a few, they'll need AAAAA (the two extra As might just come from being high-profile, not necessarily quality) (Halo, Final Fantasy main series, Gran Turismo, etc.) titles if they want system-sellers.

 Final Fantasy versus XIII if you don't put that on the PS3 list you'd be crazy.

I think the idea of what a system seller is subjective. Gears 2 and Resistance 2 are sequel to next gen sequels how many systems can they sell.

Looks better now.

ps3 needs resistance 2 and killzone 2.

maybe add valkyrie chronicles and diseaga 3 (rpg lovers would buy the system for those) and maybe even white knight chronicles

as for 360 i dunno if i would include gears 2 (i dont think it will sell many more, other than already gears fans will buy it) but add lost odyssey and maybe tales of vesperia (again rpg fans buy systems for those)

Pretty good list.

I think fallout 3 will be big but maybe not a system seller.  Left 4 dead could be a huge IP and be a system seller, valve ussually hits it out of the park

You should add Gran Turismo 5: Prologue to the PS3 list. It moved thousands of PS3's in Europe and Japan.

Also Resistance 2 for the PS3. 8 player co-op and 60 player online.

Hmm.Motorstorm.Maybe.
