Dude, it's an RPG, obvious solution: dice roll.

D20? D6?

Go with the dodecahedron.

Good idea...it gives rise for more choices.

How about 3D6? That way you could 'weight' certain choices, so that ones that you are more partial to are weighted more strongly by placing them in the middle range and the less appealing choices to the extremes...

If you need weighted choices then you've already made your decision and just aren't admitting it. I always make my daughter play eeny-meeny and if she is disappointed by what it lands on, that means she really wanted the other option, she should take that, simple, no?:)

Unfortunately I'm the sort to be disappointed by either result. :D Consider it a trait of being a Libran, if you consider that to any way being a factor of course, either way I'm notorious for my indecisiveness!

Libra FTW!

U a libra? SO am I.

It depends on the game. For something like Icewind Dale it's difficult to refrain from doing so, since there's little point in saddling your party members with mediocre stats since the game is aggressively hack-and-slash with minimal "role-playing" elements. Planescape Torment was a noble effort in a notorious min/max-centered system (AD&D 2ed) to combat it. And I appreciated efforts in other games like Fallout 2, which no longer used Charisma as a "dump stat." Though people still abused the "gifted" trait to high heaven.

In games like Arcanum I think min/maxing it more difficult to pull off due to your finite and precious few amount of points to allocate. Though some people did so anyway with absurdly powerful mages with a hugely inflated will power stat using just a few low-level spells. Powergamers usually doggedly find a way to make the cRPG experience all about stats, unless it's something stat-less, like "Call of Cthulhu: Dark Corners of the Earth."

Scorpio stings Libra.
Libra takes 10,000 points of damage.
Libra dies.
