Halo 3

So I got Halo 3 today (my dad bought it from the Microsoft company store :)). I just started the Halo 1 campaign a few weeks ago though, so I'm not going to try Halo 3 campaign until I finish 1 and 2.

Anyway, first impressions of it from playing multiplayer: the graphics are of course very good and the new weapons are really fun to play with. But — and I don't know if anyone else has experienced this — my eyes get really tired from trying to play Halo 3, and I'm much more confused and disoriented in battles than if I were playing Halo 1. I have the same problem with Halo 2. This could be because the FOV has decreased since Halo 1, or maybe because the graphics are more complex. Or it could be because I'm just generally tired today. Time will tell...
