Well designed first-person mysteries
Apparently this game started life as a Skyrim mod but I've never tried it in that form. Aside from the well-handled, first person point of view, WSAD-style movement, and pretty graphics, I didn't notice many other similarities between Skyrim and The Forgotten City.
Instead of months of journeying around a vast, open world, the player spends the entire game in one day's events within a very richly detailed (though comparatively small) city populated with a dozen or two well fleshed out non-player characters.
Without spoilers, a potential world-ending event occurs at the end of the day unless the player can figure out how to avoid it (and earlier if the player bumbles into it), with a few exceptions, the player must flee, the world is completely reset, and the same day begins again. Those exceptions make things really interesting -- the player keeps his/her inventory and knowledge, some plot points resolved on the previous day remain resolved, etc. The game is smartly written enough to avoid almost all feeling of repetition, though, by letting the player save time by delegating known tasks to NPCs, skip though dialog trees with oracular comments like "...yes, we've had this discussion before..." etc.
There are four possible endings, each of which can eventually be explored via save files, and all of which are probably worth checking out. I recall three primary mysteries (among dozens of cleverly interrelated sidequests), there was an abduction, an election, and a religio-philosophical puzzle. I'm sure this would vary based on play style and quest order. The plot held criminals both petty and mastermind, but I never encountered anything real-world-sinister.
There is a bit of combat (mostly archery), but, by far, exploration and witty discussion is how to progress. There were a few things that bugged me, the occasional invisible walls, catchall inventory, etc., but these were minor gripes that didn't really hurt gameplay.
