The last decade of TSR produced an incredible flowering of creativity: Birthright, Time of the Dragon (Taladas), Ravenloft, Dark Sun, Al-Qadim, Hollow Word, Planescape, Spelljammer. Too bad they were losing money hand over fist while doing it.
Yeah. I'm still impressed they managed to push out so many lines.
Out of all these, Ravenloft and Planescape are two of my favorites. I haven't explored Dark Sun yet but I like the idea of a post apocalyptic low magic world.
Birthright seems like some interesting, obscure product that TSR pushed out back in the day when there was diversity in them.
