Re: What have I missed?
Hmmmm...... Well, without narrowing it down to genre I'd go with: Hero System 5th, Dark Champions, The Ultimate Martial Artist, The Ultimate Vehicle, and Star Hero.
That would cover pretty much every Tech/Action/Sci-Fi movie angle.
If you were thinking Fantasy, I'd drop Dark Champions, The Ultimate Vehicle, and Star Hero and replace with Fantasy Hero, Hero System Beastiary, and Fantasy Hero Grimore.
Hmmm.... I might also recommend The Ultimate Skill and The Combat Handbook.
