No game will ever kill another game, that's not how it works. Every game has a playerbase. Ultima Online, Everquest, DAoC, Runescape and even Meridian 59 are still going and two of those are around 18 years old and still have a healthy playerbase. Even Ride to Hell: Retribution has some people that enjoy it ... crazy people but they play it just the same. Bloodborne is an entirely different game to Destiny. Putting that aside, a lot of people play more than one game anyway. I can't play one game day in, day out., I got burnt out and bored if I do it that way. I play Destiny for a bit then switch to Warframe, DA:I, FF:ARR or Planetside 2 (which is out on PS4 at some point, hopefully soon, which will save me playing on 2 machines). The only thing that will kill Destiny is Destiny. If Bungie does something to annoy enough of the playerbase that they leave. In every single game, players come and players go. If I was to stop playing right now the game would do just fine without me.
