Shameless plug: last month while travelling, I kept walking around a new city and realizing later that I’d passed places with great stories without knowing. Many Wikipedia articles have coordinates, so I thought they could become cards you collect by physically walking there. Each card credits and links back to the article.
I’m not sure it helps with the “AI absorbs it, nobody visits” problem, but every card links to the page, and I think players will go read them to understand what they've just collected.
I also suspect a lot of collectors like correcting things. I know “I was there” isn’t a citable source (see the OSM post box story above), but photos are a real contribution: many Wikipedia photos are poor or outdated, and I’d like players to be able to submit theirs to Commons in the future.
