2e is my favorite iteration of D&D, and I've long harbored a desire to create an OSR version of it with some rules cleaning.
A quick Google turned up a reddit thread, which turned up this:I can't believe that there's not an OSR D&D out there for everyone by now...here are some random thoughts
Percentile strength never made sense to me. What can't a stronger guy just have strength 19, which is greater than 18?
I don't think it's all that huge. It effects the notation for a handful of magic items, plus some gods!It does make sense, but it also causes a huge ripple effect in the game.
Not really. Most monsters don't have ability scores other than Intelligence.It does make sense, but it also causes a huge ripple effect in the game.
I think it would be cleaner to have a common STR chart and give fighters a bonus to their STR stat.What if, instead of percentile strength, warriors got a different strength bonus than other classes a la the constitution bonuses? For example, a strength of 17 for a fighter gives you +2/+3 instead of +1/+1 for other classes?
