To be more specific, something you would do when you have too much time on your hands. Or if you're like me, make things you wouldn't make but you did anyways.

Really, anything can count.

An example from me is playing games in their one-life modes and crap:

Normally when it came to one-life modes in games, I just tell myself to not bother, but I decided to go ahead with DOOM for an achievement. Let's just say I went father than I thought, then when I reached the end of the game, well, I outdoned myself. Although, I was told that the AI was updated to be more accurate in tracking the player and reacting much more quickly, so if I did Ultra-Nightmare now, I probably would of died much earlier on.

Then again, what am I telling myself, I'm a console peasant, then again, I'm the same guy who platinumed Resistance 2, Killzone 2, Arkham Origins, Sonic Unleashed, and some other games, maybe I'll do Furi next, though that game hurts my eyes.

Anyways, what do you do in your free time?
