5x5 - Action-based system toolkit. Anime-style artwork and a smooth template system.
Clockwork - Steampunk cowboys. On one page. You can't say fairer than that.
Mini Six Bare Bones - Open D6, cinematic in the vein of Star Wars but much more to it. Remember when West End Games put out all those movie tie-ins? Hack your own version. Anti-Paladin Games needs more submitted settings and an Inception-based Mini Six would be interesting.
