XD20 Roleplaying System (1st & 2nd Ed.)
A streamlined roleplaying system for running adventures in any setting, from dungeon crawls to unusual crossover scenarios. Players create characters, resolve actions with a twenty-sided die, and face challenges guided by a game master. The basic rules emphasize quick teaching and play, while the included advanced edition adds more detail and complexity.
基于属性/数值（STR、CON、PER 等）骰子（主要为 d20）基于描述（更偏叙事而非骰子）
免费，支持网页、Android 和 iOS
