Guitar Hero 3:
Lag is caused by the HDtv being used, there are options to adjust this to better settings. The graphics are better than other Guitar Heros and that isn't really up for debate. The animations are much worse in GH3. The gameplay is the same as before, which is to say that it remains boring.

Halo 3:
The field of view is fine, and the same as Bioshock or anything else. Putting the crosshair lower prevents you from staring at the ground as much as you would otherwise and is for the most part a good design decision. Some of the guns take up a lot of visual room, but they have very few shots and do a lot of damage to compensate. The AI and gameplay of Halo 3 is better than Bioshock in so many ways that this is apparently a faith-based argument and there's no reason for me to pursue it any further!

Marathon:
Is also better than Bioshock.
