I'd rather use AW 2d6+ single digit bonuses, but some players in my group keep asking me for a system that could handle bigger numbers. They want to keep leveling up forever. I could use d20 or d100 but the thing is that :
1) I want to make a cheap game that I can sell in my country; and the only thing you can get here anywhere are common d6.
2) Most players would be new to the hobbie and I found out that if I can appeal to the MMORPGs atmosphere on the mechanics its easier for them to understand and feel comfortable with the game.
3) I've played games that use pools of d6. They are terrific, but these ain't my group's thing, and I'm not used to design thing around those.
Does anyone know of a functional tested d66 game? I'm not even sure about what the probability curves are for that and how far could the bonuses go. I thought I could give players +30 at most, but now I'm not so sure.
Also, one of the players has this thing about numbers in the game; he loves to powergame in order to make sure that his character will accomplish one sigle thing 98% of the time or better. But then he relaxes and roleplays it. He just can't stand that my designs usually give the players a 50/50 chance at high levels against the highest difficulty, even when I won't be using this degree of difficulty often. Strangely, he's okey if the GM just says "no, you can't beat this guy because of reasons right now", though he has pushed a GM before by gaming the system or even the GM plot in meta, but only when said GM used really poor excuses for railroading insted of being honest and say it was railroading.
This player is also a good friend of mine and I'd really like to either get how he gets his fun from this to make a game to his liking or find a way to compromise and make a game that at least he can stand playing. I already got a couple ideas for this, but I would like to hear some other opinions on the subject. Thanks for your time!
