i think it will sell between 3 and 4m lifetime

Pacifica is Mario Kart for the PS3 only better graphics, better physics and better smashes -
Mario Kart has an attachment of ~7million in 30 million , Pacifica will do similar on PS3 - so expect ~3.5 million (around half the sales of mario Kart Wii).

It may be higher as unlike nintendos platform there are less casual games on Ps3 to compete with so could go 4+ mill - When Sony bought evolution studios they picked a winner.

Motorstorm Demo is often used for promoting PS3 in stores because it attracts people and plays well. Pacifica is the first full price game >$20 i will buy since purchasing my combination blu-ray player/room convection heater.

Re: Resistance it's total crap you can't use a mouse and it's motion support is a joke, even the very worst FPS games on the PC have vastly superior gameplay thanks to the mouse and keyboard support. FPS games and thumb controllers just don't work together.

first week WW 1.2 millions
lifetime ww 4.5 millions

4 million lifetime sales

Resistance is not a bad game, it is just you dont like console shooters, so it is no worse than any other FPSs on consoles for you
