Well, I can't help but plug myself I guess. I have built a Dragonball TTRPG system that I'm currently hosting 2 campaigns for, and the game is still under development so more things do get added (and some things gets changed and re-balanced, if that is a problem) The system is entirely of my own make, and is meant to as accurately depict Dragonball canon as I can (so yes, a super saiyan actually does increase all your stats by x50). If this sounds interesting to people, send me a message and your discord name and I could get you into my dragonball discord group. I've been thinking about starting a new campaign anyway. Edit: My current rulebook is at 490 pages long, and of course it's not mandatory reading: We're very newbie friendly, and other than me, there's like 3-4 other players that likes helping out. I would adapt a 'learn-as-you-play' thing, having a tutorial session at first. (And besides, like half of that is just a list of different features and techniques. Like a list of spells in D&D, most of those you'll never use on a single character anyway)
