I actually bought a couple of PS3 games yesterday. FO3 GOTY version and FO:NV Ultimate Edition. They're both cheap and I've never played them on PS3 before. As the new generation consoles continue to grow in market share I expect some really good deals on PS3 titles. Just yesterday I saw Assassins Creed 4 for just $14.
BTW, the DS4 controller doesn't work for VATS on FO3.
