It's not entirely uncommon to have TCP on the backend even for AAA games.

Interesting. I know World of Warcraft uses TCP, but I imagine it's less "real-time" than shooters (ie: no hitscan) so a few dropped packets wouldn't have a huge impact (ie. if you're standing casting a spell for 2sec, the game can recover the lag easily). Didn't know some shooters used TCP
