and the extra work is ok with some systems, BESM by the very nature of the Anime it tries to emulate means that some outrageous stuff fits just like Feng Shui, keep in mind that there is a difference between power creep and munchkinizing... its subtle but very real. A munchkin can take advantage of power creep, but power creep affects everyone. Many games now focus on taking out the power creep or making combat realistic and very deadly for players Unknown Armies, Sword and Sorcery, Harn and others. I dont think Power creep is as bad a problem as it has been for Palladiums Rifts, but It is an annoyance that combined with the buying a new core book ever couple of years makes D20 less desireable for me. Oddly I dont hate D20, I really liked Human Heads stuff for it (Redhurst) and Kenzer has a really nice set of books for it too (Kalamar) I just dont think it would be my game of games...
I have a question though, at the store yesterday I saw that Mongoose is publishing OGL rpgs and not D20. Whats the difference?
It seemed that they included the player info, in both OGL Ancients and Horror. It looks like you dont even need a single Wizards of the Coast book to play if this is the case are they still really D20?
Oh I almost forgot, I agree with Erics assertion that d20 mods poorly for sci-fi games... but disagree with it not working for horror games. Horror I think is just a very hard to pull of genre. Your either good at making your players squeel "mommy take me home away from all this" or you arn't.
