I am all for stats in most RPs, even if they're relatively simple ones. There's a point to be made for freeform, but statistics are a big help when you need to figure out what would happen if you needed to say, do your Big Bang Attack and then the person used a dodge. how well did they dodge? Would they be fast enough to even dodge?

Vs. Mooks and NPC enemies you can say "Yes", but if there's another PC on the other end, it's a question that needs answering in a legitimate fashion
