Oh MW and Halo are definitely good games if you care at all about multiplayer. It seems kinda ridiculous to even criticize those games if you've never really gotten into that side of them since that's probably the main reason they're so popular.
That's actually a fairly decent list all around though. Every game on there is good for it's genre. I guess you could criticize the lack of JRPGS but I don't play them so I have no idea how they stack up.
As far as multiplatform titles go, I guess it's fair to compare their graphics and features between consoles (PS3, Wii, 360) but you just can't compare it to PC. You pay more for newer hardware so of course you get a better looking game, the costs/benefits are totally different for the consumers.
