Destiny 2 Gambit or Crucible Private Match I think you could make a Tournament out of them.
I played Destiny 2 at the last event and the game was complaining about being on Strict NAT. Also, we now know Bungie is moving the PC version from Battle.net to Steam and this upcoming LAN is a few days before the switch. That said, I would love to see Destiny 2 as a tourney.
