I've never really been into them so they definitely are not one of my strong points.
I used to love them as a kid, especially Crash and Spyro. I guess the closest I get now are jumping puzzles in Assassin's Creed and Unchartered. I get 'em done, but it may take a couple of attempts at some of the more fiendish jumps.
I was much better when I was younger. I picked up Super Mario World recently after not having played it for years and it was a pretty depressing experience.
We had a Crash Bandicoot 2 drinking game a while back, I was the least drunk. So I'm going to use that as measuring device and say I was a'ight.
If you die you take a shot then pass to the next player. The more you die the more you drink the worse you get, it's a cycle really.
