Star Wars TTRPG

Fair enough

A bit unrelated but would learning other d6 systems like AD&D 2e transfer over to stuff like GURPS or Star Wars d6? My original idea was to use 2e for fantasy style settings and Starwars for sci fi stuff.

There was a d20 Star Wars that's literally the basis for the KOTOR and KOTOR 2 games.
It's neither bad nor great, but it worked alright.

West End Games' d6 system is better, imo.

AD&D 2e is D20.

Huh? No it isn't. D20 is what 3.X and beyond was based on. There are some D20 AD&D 2E retroclones, though.

It's the die you use for the majority of things including attack rolls, therefore it's a D20 game.
There being a "D20 system" is unrelated to this.

When people say "d20" in this context they are usually referring to the system.
AD&D 1e or 2e wasn't such a system. I started with Basic in the early 80s, and I still laugh at the absurdity of the "THAC0" nonsense that was needed.
(I created a d20+adds with increasing ACs independently in the late 80s, by the way. It was obvious. I suspect many people made a version.)
