30 or 32 pt buy
I like a 30 or 32 buy. It allows everyone to have "heroic" characters without it getting out of hand, and everyone then starts on an even field.
I REALLY like the point system because in my old 2e gaming group, we sometimes had issues because because someone would roll ridiculous scores and all hell would break loose when that person became an elven duel wielding blinder of death with the mightly composite bow that could topple towers from a mile away (well a bit of an exaggeration but it generally wasn't fun none-the-less).
The point buy system seems to keep the whiners away, yet at the same time it gives players a lot of room to work with.
