Flexor the Mighty!
18/100 Strength!
This underscores an element of the discussion that I think is important: the difference between complexity in the core system of a game (say, Shadowrun) and complexity that emerges from lots of options (D&D 3.x is a good example here, I think).
Yeah, the core system of D20 wasn't very complex. It was the number of modifiers that were changing round by round. And depending on the group that could be a real PITA as people would lose track of what was what and how feat X applied to situation Y.
