I've been working on a system that converts roguelike games to a workable tabletop RPG ruleset.
I initially tested the system with DoomRL. I'd like to release the rules to play DoomRL within the system, playable standalone for free. Ideally I'd like be able to use the wiki documentation for explanation of most of the mechanics.
The issue is I'm not sure what all copyleft licenses would apply to the work. Since I'm only copying wiki documentation does only that license apply or do I cite both the wiki and the game as sources? How to go about linking them, and what if any would apply to the system I've made removed from the DRL IP?
I also plan on making similar adaptations of other games under the same overarching system. Will the rights of DRL conflict with the possible rights of any of the others if it effects the core system license as well?
I know I'm essentially making a mod/fan game and nobody is going litigate regardless, but I also don't want to plagiarize.
