Best Table Top Role Playing Games that are NOT Dungeons & Dragons (D & D)
Many of these are older, out of print, or otherwise hard to find. There are a great crop of current games as well but I only have experience with a few. All of the ones on this list I've played and enjoyed over the years.
Open Source Gaming License (OGL) or D20 clone of D&D. Very popular
Pathfinder in Space
3. Star Frontiers
Beginner Friendly space opera but lots of potential
Somewhat rules heavy galaxy spanning exploration
5. Twilight 2000
post WW III from an 80s US dominant point of view
Generic Universal Role Playing System with optional rules books designed for practically every genre.
When Orcs sling magic and Elves are the ultimate hackers
8. Villains & Vigilantes
Great titular word play for a superhero based TRPG
9. Gamma World
A fun sci-fi version of post-nuclear mutant powers. But no Bruce Banner.
You hasn't wanted to role-play as Roger Rabbit?
