Speedrunning is pretty much the opposite of how I like to play games. I prefer taking my time and seeing everything in the game. Though this is true, I would love to try something new with my gaming. My Steam library comprises most of the games I can speedrun currently (besides free games out there in the world) and is visible on my profile. What would you guys recommend I try to do in the fast speediness ways?

Super Meat Boy is a good start however I see you haven't played it much.

L4D, Portal and Issac are all decent games to run! Welcome!

+1 for Super Meat Boy. It's just a great fit for speedrunning.
