All depends what your into!
Black ops 3 or Halo if your competitive multiplayer person (Black ops 3 Preferred)
Sports games aren't bad if your a sports person. (Madden person here)
Others - Just Cause or Fallout 4.
Good Luck
Honestly its gotta be the xp rates. Seeing the gains just makes me want to play more and get that 99 range! Can't wait to be able to pk tho!
How about you @Sp33dy20?
