This is the only TTRPG I ever played as a kid, and that only a couple of times, but it was very influential. So much of its source material was either official or became official in the old EU, to the point where the original Zahn trilogy had their own sourcebooks released. There was no wookiepeedia, there was “that kid down the street who knows the shit from the RPG books.” I even coded a QBasic version of Sabacc based on the WEG rules, though the “AI” was nothing more than a cardback blackjack algorithm.
