I would like to see it succeed, but everything so far leads me to belive the arena shooter is stuck in a nostalgia bubble where it is simply too hard for a casual player to pick up. Similar to Starcraft 1v1, nobody remebers the 1v1 games, but everyone played Hunters or team games.
Necro thread -- I've been playing this and having a blast. If you're a fan of Quake 3, or Rocket Arena (mod) then give it a shot! It's free on the Epic Games store.
