Regardless of the controls, CoD4 was a better shooter, the gameplay was much more fun, the feel was there. MoHH2 well yea..
I can't really say, I usually use my ps3 to browse the web and watch movies or play my old ps2 games, the Wii just to play games and by VC games from time to time, wish they would let you watch movies from your SD card at least.
Either way I don't mind the friend code, but I don't like that Brawl uses a seperate code than the Wii - it's kind of annoying, I guess in the case you lose your Wii you can still play with the same friends list.
Any way, I don't like the current HDD capacity, it works it's fast but once Wiiware comes out, that baby is toast for me.
