I think I like the Mosin-Nagant more than the KAR98 (if only because when you bolt the Mosin, a shell comes flying out and that looks badass) and I like the Type-99 more than the MG42 (once you get over the horrid iron sights, the T99 is amazing)...but! The FG42 is my new favorite weapon in any CoD. God damn that thing is a beast! Put Sleight of Hand and Bandolier on that bad boy and you're ready to destroy leagues of noobs. Best part is that with SoH, it reloads so damn fast that I've had time to reload 3 times in a single close quarters firefight!
It's too bad the iron sights are a little off (the damage markers appear slightly up to the right of the point on the sight), but that doesn't cause too much trouble. Overall, though, I might agree that this is the tightest of the modern CoD's - most things have been thought through and designed well, unlike IW games. I just hope Treyarch have the balls (and Activision permission) to strip some CoD "classics" like Martyrdom, Last Stand, Juggernaut and noobtubes from Black Ops. Those are like the only things that really annoy me about WaW.
