Assassin's Creed IV: Black Flag since it was released for free on the Xbox One. I already have experience from when it was free on the 360, so there isn't anything really "new" for me to experience. Still playing Halo: TMCC almost daily. I've recently gotten into playing CE the way it was meant to be played (Doubles!!) and my partner and I have been doing quite well. Throw in some Halo 3 and BTB, and I'm having a pretty good time. Pool Nation FX just got an update that removed the point system for some reason, so multiplayer matches aren't as fulfilling.
