You cant really compare some of these games to the ps3 because all of these are second generation 360 games and the deveopers are familar with the system and how to make games.

If you want a fair comparison compare First Generation 360 games to first generation ps3 games and or second generation 360 games agenst second generation ps3 games.

And all of those games were multi-platform so they are obviously going to be close you should compare PS3 exsclusives to 360 exslusives like when next year rolls around compare a second generation ps3 game like Motorstorm to a second generation like Gears.
