Should we mark them as all duplicates of each other? No. They are asking about different symbols, so marking them as duplicates of each other doesn't make sense.
As stated in this question's comments, we should create a canonical instead that contains all possible symbols, then mark all the symbol questions as duplicate of that instead.
According to a comment on this answer, symbols vary between games, so we may instead have to tell users to consult the game creator.
I'd like to invite Penguin or galacticninjaWe have also agreed that the best user to create said canonical as original posters, but I'dwould be happya Roblox player themselves, so if you would like to makevolunteer yourself, go ahead and create it myself if you'd rather not. Be sure to explain clearly why the icons are game-specific, and give examples of how two of the same symbol might mean different things in different games.
