Duff, in terms of (graphical) polish, Killzone and Uncharted, along with God of War (which ironically has just announced multiplayer) are generally considered the best looking games on consoles. In my opinion, Killzone has a brilliant multiplayer. I'd say try the free Killzone 3 MP, unlike KZ2 it has the COD feel you're used to. As for Uncharted, which can
be described as a shooter, it's my favourite MP this generation. So much fun. Did you try the Twisted Metal demo? That's technically polished in that it, amongst all the high speed carnage and mayhem, very impressively always keeps a rock solid 60 fps online. Also, obviously, a ton of fun.
Yes, I agree with you. Hold fire on the next Xbox and wait for the PS4. For a good while now it seems MS have less and less interest in the gamer. Very few exclusives, a focus on the useless Kinect, more and more apps (that are free elsewhere) hidden behind a paywall, and now about to include 30 second adverts before some of those apps. Frankly, adding even more ads to a paid service is insulting. Just look at that cluttered, slow, cumbersome dash. Adverts in your face everywhere. In contrast, the XMB, clean, sleek, elegant, no wading through rubbish to get to, what should be the prime focus of these machines...the games. Remember Microsoft's E3 conference last year? It was awful. Embarrassingly so. This year will be no different.
In terms of the 'online experience' you're looking for on the PS4, you only have to look at the Vita to know they'll have cross game chat etc. Personally, I'm not interested in party chat and all that stuff, but just as the Vita has it, so will the PS4. And, I strongly suspect it'll remain free.
Resistance 3. You must play it! The best FPS I've played this generation. Really involving story, great graphics (sometimes incredible), atmosphere by the bucketload, fantastic pacing, wonderful level design, lots of really intense memorable set pieces, a rewarding weapon leveling system, unlocks, old school health pick ups, and the best collection of brilliant weapons in any shooter I've ever played. Completed it on Difficult, now I'm going through my run on Superhuman difficulty in mirror mode to get the Platinum. Yeah, listen to me and Chris...buy this game!
