Back in late summer of '09 after E3 announced that the price was going down to $199.99 for the arcade bundle. I had no interest in the online component at the time and just wanted to wait until the price point of under $200.
I bought "Tales of Vesperia" and "Lost Odyssey" on that day. Enjoyed both but never finished either, so I guess I bought if for price and JRPG's.
Rare+Bethesda+Bioware. Only Bioware has disappointed, despite the haters for this first two. This was actually my favorite generation for Rare and Bethesda both. I'll take Kameo/Pinata/KS/and yes even PD0 over all the old school stuff which has all aged horribly, and Skyrim/FO3 over Morrowind or Daggerfall. Bioware.... ugh, I don't even want to talk about them. Obsidian are here now and CDRP has joined them. I don't have to rely on Bioware for meatier narrative in my RPGs anymore, let them dumb their games down and have all the worst writing in the history of games they want. I ain't even mad, they've been surpassed.
The writing was on the wall with Bioware the minute you could completely void all of your decisions with one choice in KOTOR.
more exclusive games I like (Rumble Roses XX, Bullet Witch, Chromehounds, Project Gotham Racing 3 and 4, Perfect Dark Zero, Kameo, Project Sylpheed, Test Drive Unlimited etc.)
multiplatform games I like were/are usually better on 360 (Sonic 06, Bayonetta etc.)
the prices of games I like being generally cheaper than PS3 games I like (this may be different in different places but here where I live and buy my games 360 games are in general cheaper than PS3 games, with some but very few exceptions)
I had the opportunity to buy my 360 with some games and controllers cheap second-hand
The fact that PS3 has a lot more positives than 360 as a console and what the console can do beside just playing the games means I still want a PS3 as well, but as far as the games go I'm satisfied with having a 360 only. The only exclusive I want for PS3 is Gundam Crossfire anyway. The other exclusives, like MGS4, Resistance 1, 2 and 3 , Killzone 2 and 3, Heavenly Sword etc. are games I'd probably end up getting if I had a PS3, but I don't want them enough to warrant buying a console for them, not even combined, Gundam Crossfire is the only game so far that I've liked enough to want a PS3 for and I don't buy a console unless there are at least two games I want for it or if I can find it for a really good deal.
