I'm patiently waiting for a game which lets you play in real-life environments. Like an FPS or racing or sim game that lets me play in my favorite cities, or better yet, my favorite towns.

Doesn't even have to be accurate, although it probably needs to look realistic. Like I really only need the aesthetics, not the specific placement / distance of buildings. As long as I get the "feel" of familiar cities / nature that would be awesome.

Geoguessr is already a popular game, and all you do is travel around a location and guess where it is.
