Quote from: Black Vulmea;582543I could run an awful lot of things with d20 Modern, my favorite iteration of d20 games.

I rather liked the d20 Modern book but always found it hard getting players for it. A lot of d20 players in my experience are the last ones to be interested in a modern setting.

A cleaned up second edition of d20 Modern would have been fantastic. I particularly liked the d20 Apocalypse and d20 Future books.

A lot depends on "which" version of D20 you mean. True 20 was decent, and solid, and can do more than straight D&D. While M&M 1E was even better at that for the most part.

I wish M&M 2e was more like a refined 1e. 2e just seemed to make my eyes glaze over half the time. 1e I loved from the time I first saw it in the store.

Oh, I know. I tried so hard to keep them from making  it overly complex, but was drowned out during playtests--partly by being busy with life, partly because it was full of ex-Hero fans. (No, not all of them, but enough  of them were there who basically wanted Hero like subsystems in the game.)

d20 has all of the problems that D&D has basically always had.  The extremely abstract HP and AC mechanics, with armor making you harder to hit, et cetera.  The level mechanics which result in level 2 characters being very near twice as powerful as level 1 characters.

If none of that stuff is detrimental to the kind of game you are trying to build I don't see where d20 probably wouldn't work for you.

I do think some games could probably benefit from a much shallower curve in PC advancement, and less abstract combat resolution though.  If I were to do a "Fantasy Heartbreaker", or similarly abstract action/adventure oriented game I'd almost assuredly draw heavy inspiration from d20 though.

I'm sure there are games that use d20 that aren't primarily action/adventure oriented that are good (I've got d20 CoC, but have never played it) but can't imagine that they couldn't have been better designed from the ground up.
