Easily:
- Rocket League: > 1700 Hours. (Still ranked Diamond though, lol)
- Team Fortress 2 / Left 4 Dead 1 & 2: sub-1000 hours, each.
- Subspace/Continuum: over 1000 hours for sure, but nobody counted. Tried jumping back in the game just for fun, i'm back to square one "what's the button to attach?". I was a Trench Wars/Extreme Games pub guy.
