it just depends on your personal taste…i was an avid 360 fan boy…ive played most of the major hits for the 360, i have both a 360 and a ps3(and a wii…not that it matters) and i personally like the ps3 more,games are cheaper than their 360 counter parts,online is free…games are typically over rated by people on the 360…gears of war 2 was good but they update the game way too often…so your never use to the game online…they also changed the ranking system on it and halo 3(which made me quite angry)

you will get nickled and dimed with a 360 because of the points store
if your into dlc

mass effect well…i didn’t like it much

the only real problems i have with the ps3 are
sometimes the frame rate is slower than the 360 version(which usually is fixed)
and nobody i know has one so i have to meet new people online(which i am sorta shy so it doesn’t work out too well)

there are add ons for every game pretty much

bethesda(creators of fallout 3) have confirmed the dlc for the ps3 version of fall out…first add on comes out late this month

and well…i guess your out of luck as far as gta goes
