While i'd not exactly call halo anniversary equal to a new title, it certainly had infinitely more effort put into it than these cheap upscale ports, and keep in mind I own the collections that matter on the ps3 sans god of war (as I hate those), I certainly don't look at them like new releases though. They take old ps2 games and upscale them and jack up the framerate, oh and trophies.
Maybe it's just me, i'll take a graphics overhaul over a generic bump the resolution and framerate and call it a day effort, at least with that method you get something seemingly different visually instead of just cleaner. Things like REmake or conker on xbox are much cooler than anything sony is outputting with these things. I don't mind that they exist for the ones who never got to play them or enthusiast, but it's a pretty cheap way to pad your list considering what they are.
I'm not really trying to defend Microsofts 1st party right now though, they've had a pretty touch and go amount of quality the last couple years, but they seem to pull out enough heavy hitters combined with excellent third party support coupled with xbox live to make it worthwhile to own the thing for most. I think people judging the next xbox based on the way things are this moment are a bit foolish though, it's like saying I won't buy a wii U because nintendo decided to drop wii support in good bulk 2 years before the new system hit, Wii U to have no games?
Another thing worth noting is taste, something people seem to forget exist when having list wars about a console being truly shit. The ps3 has a really diverse lineup of games that looks impressive on paper, but for people like myself who play a wide array of titles on all systems it's still hard to list a ton of exclusives I love for it compared to ones I have on 360, the ps3 just doesn't hit it out of the park for everyone. Infamous is a good series as is ratchet, but resistance is about as generic and dull as any FPS series I can recall, I put it up there with turok on the 360/ps3, truly bland. Twisted metal is a nice revival and the last story will be awesome if it ever releases, but even the most darling series on ps3 like uncharted or god of war, I only see limited value in them. Uncharted is like a great 8.0 series to me that relies too much on drake going WHOA OH to no real danger while solving lamer than resident evil 1 puzzles and doing shooting that while fun enough is not nearly as fun as top tier shooters like RE4 or gears of war. Graphics and story direction aside of course as those are ace, and god of war is well, trash compared to the likes of ninja gaiden or bayonetta. Again personal opinion. People champion Littlebigplanet, I think as games they are vastly inferior to other 2d platformers like klonoa or mario on the wii.
People see these opinions as trolling, but I could see why people would hate viva pinata, halo, gears, kinect sports and crackdown too, but I love them all and have at least played all the games I choose to like or shit on. These days, third parties are what seem to be hitting it out of the park for me aside the odd halo, gears or infamous, and those are often best played on the 360, especially since the controller is much more comfortable, and with third party output being pretty incredible to this point, I don't really see how someone can hate the 360 or ps3, but could see one or the other being redundant. Either way we're going on year 7 of that consoles life and there is still plenty to play on it.
