What are the other reasons?

Conan D20 Atlantean Edition
Call of Cthulhu D20
Everquest D20

I picked these because I think they did a great job of altering the system to meet the desired setting and genre.

Star Wars Saga
True 20
Fantasy Craft

Dungeon Crawl Classics.

Its been a while TBH. I know I didn't like the Temptress class very much. They also added more options and complexity in some areas that I didn't think was necessarily a good thing.

I must say I find all the love for FantasyCraft quite unfathomable.
YMMV I suppose.

I like Fantasycraft holistically; it just looks like a neat system. But when you break it down, seems like a ton of overhead to basically do dungeon crawls. While I'm happy I have the game, I'll probably never play it.

Wheel of Time d20
The Original Darwin's World
Stargate SG-1

If we're counting DCC as a D20 game, then I'll switch my answer to that as well.

I feel the exact same way about Spycraft. I really want to love it. I really like it. but when I sit down with it and start bashing. It just feels so tedious, and overwhelming.

Which version? The original Spycraft is pretty decent, but 2.0 made things overly complex.

Definitely speaking of 2.0. I also made the mistake of getting the pocket edition, stupid tiny ass text hurts aging mans eyes. Shakes my fist at the book, "Damn you Spycraft!"

I do like the game dont get the wrong idea. Its just too much.

Quote from: Novastar;671792Hell, even including 3.5 & PF, I'd still pick Star Wars Saga Edition.

Am I the only one who kind of liked d20 for everything except D&D?

I'm not a fan of PF or 3.x, but there are a few other D20 games I think are pretty good, so I guess that I'm kind of in the same boat.

Oh, I forgot: the Pathfinder Beginner Box. A complete ruleset with many of d20 good things and none of the bad.
