The latter has a well-defined excerpt and description:
Excerpt: An online or offline tool used in preparing or running a RPG.
Wiki: A device, software, online service, procedure or process used for a specific purpose in relationship to roleplaying games that is not part of the ruleset for a given rpg. Could be anything from "the Obsidian Portal campaign wiki website" to "the document called the Same Page Tool."
While the former only has an excerpt:
Physical items or digital tools that help a game run more smoothly or enhance game play in some fashion.
"Tools" also has many more questions than "game-aids". Of the existing "game-aids" questions, most seem to be about Android apps, which would seem to fall squarely in the "tools" bailiwick.
Can these be merged? Or am I missing some nuance?
If they're not merged, shouldn't the Android questions in "tools" be re-tagged to "game-aids"?
