Uhg, I rage quit only when the game is MASSIVELY unbalanced. For instance, I was trying out this F2P MOFPS named Combat Arms, I'd heard of it from a friend and it sounded alot like another F2P MOFPS named Alliance of Valiant Arms off of Steam that I'd really enjoyed, so I gave it a try. There is no Rage like starting a game with only a shit M16 and being decimated by a team with Sniper Rifles and Rocket launchers, yes I did score SOME kills, It mainly came down to:
Spawn
Run 3 seconds to wear off Invulnerability
Die Painfully
Rinse and Repeat
I thought, Oh, well that was just one round, couldn't happen again. I even bought a scope for my M16 with what money I had. Next round?
Spawn
Run 4 seconds
Die Painfully
Rinse and Repeat
-.- Only game I ever Rage Quit in my life.
