Genius-level player characters. . .
I've run a lot of different systems and continually have problems with players who create high-intellect characters.
Normally, I get by with dice rolls and handouts, "You recall that the same elements you observe here are also found in Talaxian lake water."
But even when I send GM notes, this still sort of makes the PC into a sock-puppet for GM exposition. I find it rather. . .addictive.
One of my players (a Vulcan science officer) is showing signs that he feels he cannot contribute to the game on his own. :(
Suggestions? I'd like to hear how players and Narrators have dealt with this issue.
