My initial gut reaction is to call all of you point buy lovers pussies, for being afraid to take chances. That being said, in the last year or two, my group has been playing mostly high powered games, with a roll 4d6, drop the lowest, re-roll ones, which comes out to somewhere around a 36 or 40 point buy.
But for the first ten years or so I played it was 3d6, re-roll if total modifiers is below +1. I had plenty of characters with abysmal stats. I suppose it all depends on the table. Nowadays, we're all very familiar with the ins and outs of the rules, even the obscure ones, and table time has shifted from a majority of role-play to a majority of rules lawyering. Which might have something to do with the drinking problems...or is it vice versa.
Anyways, different variants for different games, I guess.
