While I don't generally care for "live" games (I only ever pick up and play an MMO for 1-2 months max, I don't play Destiny, Dota 2 and League I used to sink a lot of time into, but it's dropped off), my friends got me into R6: Siege, and I quite like what Ubi has cultivated with that game...
..not to say they haven't tried to fuck it up, with the Starter Edition (which I'm convinced was a compromise for Smurfs/Cheaters so they can get in for cheaper, because they won't care about everything taking 800% longer to unlock) and their plan to re-release the game for $60 to try and bring the base value of the package up (thanks TO the updates it received as part of being a live game).
