As long as the PS3 has MGS4, yeah.
But there are PS3-exclusive games on the horizon which played into my purchase of the system:
Final Fantasy XIII
Final Fantasy Versus XIII
God of War 3
Resistance: Rise of Man
Gran Turismo 5
Silent Hill 5
Resident Evil 5 (rumor has it that the 360 version has been dropped by Capcom.. was met with repeated denials from Capcom, but where there's smoke there's fire.. something's up as far as that's concerned for it to pop up on several Japanese media outlets. Still.. just a rumor, and probably not true, given Capcom's multi-platformness of late, with DMC)
That's a pretty big list of exclusives.. enough to warrant owning the system.
And also.. Blu Ray. I don't have an HDTV yet (God, I wish I did... to see MGS4 in high def..
) but I probably will by this time next year. Granted, there will probably be cheaper Blu-Ray players by then, but if you've already got an HDTV, that's a big reason to own a PS3.
And, again.. my 360 is a piece of crap. There's only so much screeching noises from the system I can take at a time, even if it's not doing anything to the discs.
never was a Final Fantasy fanatic
dont care for killzone until it's proven to be as good as it should be
resistance, i can live without never having played it
GT5, that's my bro's type of game
RE5, i'll believe the rumor when it happens
Silent HIll.... eh, again another game I can live without never having played it
of your list God Of War 3 has the most interest for me. the one game that I do want is Little Big Planet
but you're right, the muther effer sure is silent like a submarine
