Have you ever done a speed run for a game ?

no... quite opposite really, I play levels repeatedly to get all the easter eggs & hidden achievements..

I did on first prototype, a bird story(1h lol), crysis 2

Does Love count? ^^

WelL,my best speedrun was in Dota2 when playing team of pushers =P

does the game Speed Runners count?

Huh. more speedrunners here than I thought. Thanks guys :)

Halo on the xbox has a few achievements on it where you pretty much have to speedrun the game. So I've done some on that.

I speedrun Minecraft,TF2 and Dota 2 kappa

Every sonic the hedgehog

Seriously, half the people who voted has done speedruns before? I'm really surprised. I always viewed it as something totally hardcore that only people with way too much time would do, especially because for most games you need to invest tons of hours on repetition to get specific parts just right. Plus, with many people having hundreds of games in a backlog that just keeps growing, I find it quite jarring that they spend so much time repeating one instead of trying out new ones.. (multiplayer games excluded, but speedruns are kind of single-player only anyway).
