Addiction to Computer Games.

[starmonkey]

I get hooked on multiplayer games (like Counterstrike or League of Legends) where you're just doing the same thing ad infinitum.

Single player games I can walk away from, mainly cause you're never "missing" out on anything, you pick up where you left off.

Thus, in the interest of a healthy life, I only play single-player games like Amnesia. Though that's damaging to the health in other ways
