*scans thread for mentions of Natural 20 Press, then winces*
Ah well, we
have only sold a few thousand copies between all our products.
Anyway, Natural 20 Press has put out three top-notch books that I've been lucky enough to work on, plus one middle-notch book that I wrote by myself, and we've got an imprint publisher who has put out about a half dozen books that I'm not really confident commenting about.
Tournaments, Fairs, & Taverns
For your campaign, I'd probably have to suggest "Tournaments, Fairs, & Taverns," currently the #1 pdf D20 product of all time at RPGNow (and quite possibly the top non-Monte Cook D20 pdf ever, *grin*). It's a sourcebook that helps game masters run the parts of adventures where PCs just want to kick back and have some fun, without requiring the hacking of monsters. Over twenty different games are presented, ranging from default rules for jousting, arm wrestling, and getting drunk, to more exotic sports like caber tossing and magical rugby.
You can buy it at
this link for $6.95, or you can wait about . . . what is it, about a month now, Doug? Mystic Eye Games liked the pdf version so much they did a print run of it, which should be coming out soon. Read reviews
here, where you'll see that TFT is tied with two other Natural 20 Press books for the top-rated pdf product. Wild Spellcraft doesn't deserve that merit (that's my book, and in hindsight it's not as good as I thought), but Four-Color to Fantasy, I think, does deserve the high rating it has.
Four-Color to Fantasy
What's Four-Color to Fantasy, you ask? FCTF (or as some people prefer 4CTF) is a fully D&D-compatible and d20 Modern compatible super powers product. You can run classic comic book superhero adventures with it if you want, or take the rules to add new powers to normal fantasy characters, like having a halfling girl with a Strength of 50 (and isn't she cute?).
You can read reviews of FCTF at the same link as above, and can buy the pdf at
this link. As of now there are no plans for a print release, but maybe some publisher out there will take interest when we release the revised edition, with rules more specifically suited for D20 Modern. This is my personal favorite book, since it leads to all kinds of interesting characters that go beyond the normal core classes, but it's not for everyone.
Others
If you're interested in alternative magic systems, you might also want to take a look at Wild Spellcraft (toolkit-style book for making magic more unpredictable and dangerous, plus a conversion of 2nd edition wild magic rules), which is okay, but not great. The Elements of Magic, which is a completely new spell system that abolishes the arcane-divine division and lets you use one set of rules to create the type of spellcaster you want. We have more on the way, but I guess I've raved enough, so I'll head off now.
