As a gamer who plays pretty much all types of games, I have quite a few skills. A lot of them are actually quite good, but only really when not timed or quickly paced (like Civilization, slower paced RPGs, Stealth games, etc.)
However, even after years and years of practice with fast paced FPS games, my reaction speed still sucks (I still get tunnel vision in games too as well as poor[ish] aiming, though not as bad).
Keep in mind that my PC sucks (like, lags on League of Legends :P). Anyone know of a website that'll help me improve in reaction time? Also sites for aiming or paying attention to many things at once help as well.
