This is one of the reasons I don't like point buys. The DM can use any system in the verse and it may or may not make sense.
Er. The same applies to ability rolling variants, actually. The DM can insist on anything from 3d6 take what you get (placed in order), to 5d6 drop 2 lowest reroll 1s (place as you like), minimum ability mod total: +9, to whatever else they deem to be appopriate for their campaign.
Personally, I have yet to find/make a point buy system I'm happy using for my campaigns, but on the other hand I've used ability arrays a couple of times (e.g., 18, 16, 13, 11, 10, 8 - ha! why, that's 36 point-buy and I hadn't even realised it!
) and that was absolutely fine with everyone.
I think I'd favour a '1-for-1' point-buy system, if I was to use one at all. So, start with a base of 3 for each ability, and add points to the abilities directly, with a pool of. . . maybe 52 points or so? That allows a degree of 'min-maxing' I know, but I think part of the GoO Role-Playing Game Manifesto applies here. Sure, at the extreme end, a character could start with 18, 18, 18, 10, 3, 3. . . but I'm sure they would have some serious problems if they did. Well, there's that, and the fact that players IMC's have rolled scores such as these (4d6 drop lowest, and
in plain view) : 18, 17, 16, 16, 13, 10 - arguably 'worse' than the 'worst' scenario possible using that hypothetical point-buy system I just described. Hm, 54 point-buy? Is that right? Well regardless, that's what someone rolled for their PC, legit.
