Oh a thread in which I can be relevant!
For me, I love role plays that involve mechanics because table top game systems give me the sugar plum wet dreams of twelve year olds who know they are getting a set of D&D books for christmas.
But I know that people generally don't like to be limited that way! SO in the RP that I'm running I promised a lot of things centered around keeping the players away from numbers, stats, math, and all that junk they don't want to figure out (much like how the pokemon games generate numbers for you. Only truly devoted trainers go all out on EVS and IVS).
Trying to get the best of both worlds: players who wanna role dice but hate the math and a GM who loves the math and the dice and the players and the story, lead me to this conclusion: I'll do all the stats and the numbers but my players will role dice and have skills, and moves, and levels. It's not terribly complicated. In fact it expands on what individual pokemon can do! (it's a mystery dungeons so the pokemon have fancy D&D-esque classes.)
At first I thought it wouldn't go too well, but now I have ... 8-9? players who are all writing great posts and don't even have to worry about stats.
