I remember back in the day of playing the original gold box Pools of Radiance - you can build your party of six characters - and it has a stat rolling generation method, where you can just roll over and over until you get stats you like...

BUT... at level 1 you can "customize your character" which lets you just manually assign stats (I think the idea was so that you could re-create your tabletop characters in the game.) - but as a kid we would always just set every stat to 18 with it.
