I've played L5R for about fifty hours this semester, and it's starting to make sense. I think I'm a better RP'er because of the experience.
I also sat down mid-session last night and scripted a program to calculate the probability of making any particular roll in L5R (including exploding dice for 9s and 10s, re-rolling 1s, and bonuses to score. It's my first-ever legit program that serves a purpose, so I feel proud.
