Like I said, it's reminiscent of Harrison Bergeron.
No. It'd be like Harrison Bergeron if I gave the charismatic player an automatic penalty to do away with his natural advantage. I'm not doing that. I'm instead urging that charismatic player to do his best. And, if he does his best, he'll be rewarded.
If the non-charismatic player does his best, he'll also be rewarded.
And the culture in general does seem to be shifting towards this conception of fair - eg I saw recently that a disabled paralympic sprinter is to be allowed to compete in the regular non-disabled olympic sprint - but he gets to use prosthetic legs to help him; the non-disabled sprinters aren't allowed prosthetic aids. He wouldn't get too far without his mechanical legs. Likewise your weaker players are assisted by a lower roleplaying bar, your stronger players are handicapped by a higher difficulty setting, so that they are all 'equal'.
There is a huge difference here.
In the Olympic games, the various players are in competition with one another. The entire point of the exercise is to see which one of them can be the top in a given activity.
At my RPG table, the players are *NOT* in competition with one another.
The Olympics and my RPG have decidedly different goals, so it should be no surprise that we don't use the same methods.
