WolfCleric said: I donna I was thinking making my own but I'm not really famlier with Roll20 but I still wanna make this I have so many ideas. Making your own system is a LOT of work, believe me. Personally I'd just use one of the many systems already available and tweek it to your needs if necessary. But hey, if you'd rather make your own, more power to ya. Perhaps think of using a system that's very easy to customize, I've already brought up M&M, but I think games like Savage Worlds or Fate are good choices too. Also, if you really want to make the game rather dark in tone I'd introduce a sanity system (or something similar). That way horrific experiences leave lasting mental scars on the characters, which should really help setting the tone. After all, in Madoka Magica they had to fight all kind of almost indescribable monstrosities that would shatter the mind of any sane person. And another thing: sacrifices. Madoka Magica was very big on the idea of having to make great sacrifices to get what you want. Perhaps do something similar, where the player character have to make great sacrifices in order to get their powers? Preferably something that leaves a lasting impact and might haunt them throughout the campaign. After all, Madoka Magica was a psychological story and a tragedy, so there has to be plenty of drama. I hope that gave you a couple of ideas to work with. Personally I'd love to play a game like this, but that probably won't happen anytime soon. But that doesn't mean I can't help other people run a game like this, right?
