its mostly the concepts behind the games that makes me go "hell no!".
and from what i understand, the theory that this games are based on cant realy be used to define the type of games that i define as roleplaying games...
basicly the games seems to rob the character of all that makes it the character.
both gurps and d20m/d&d is a bit to close to war games with their grid movement systems and all that. but these other games take it all the way out to the other extreme (story uber alles), and even more into the extreme then both gurps and d20m/d&d does towards war games.
i prefer a game where the numbers tells me something about the character and what he able and not able to do. these new style games toss this out, and for me thats basicly the same as tossing out the soul of a rpg.
no, im not a minmaxer or a munchkin, atleast not overt. i can gladly stop putting points into some skill or stat because i think that the number i have fits my view of how the character should be (given that in d20 have this kinda buildt in i may minmax it a bit more within the class. but i will pick classes for the concept, not to get the biggest BAB or similar).
in essence i prefer to call these new style games shared storytelling games or similar, not roleplaying games.
