I've only had the game for a few days. I've completed only the beach on the story mode, most of the time I'm online .
I haven't played an online FPS since 2002 (HL2 CTF, Quake 3). It's not as frantic as other online FPS, but it's still fun for me . Yeah, the skill level of many players isn't as 'l33t', but I'm pretty sure it'll improve by Christmas. A very annoying thing I see is when someone has the flag in CTF and doesn't know it.
