Also the character creator, the depth of personal freedom to make or break relationships, even the wide diversity of npc skin color is awesome. You have a ton of DND races but the NPCs feel somewhat unique from each other even when they are the same race due to the diversity of appearances. The dialogue is well written, the choices you can make are abundant, the music gets in your head, the sheer volume of class actions and customizations that highly affect the way the class plays (DND license well used), and the varying levels of difficulty allow people to approach the game from their own experience and work their way up from there.
It’s the package that sells that game.
I am American and we had these in the 90s too. I wasn’t even born the the 70s and I have seen these.
