We have a lot of questions about the spell Wish across various D&D editions, largely of the form, "I thought of X, can the Wish spell do that?" or "One of my players cast Wish and asked for X, can it do that? What should happen?"
I think we would benefit from either a single cross-edition canonical question, or one canonical question per edition, that new instances of these questions can be closed as duplicates of. This could then have a solid community wiki response covering both what Wish can do (anything) as well as what the DM should probably allow the Wish spell to do (nothing too crazy).
How does the community feel about this?
