The Forgotten City is a first-person adventure/mystery game set in an ancient Roman underground city, in which time travel is involved but I will say no more than that. It's based a mod for The Elder Scrolls V: Skyrim that was released in 2015, and was subsequently reworked and rebuilt from scratch as a standalone game over a four year period.
This is my first session with the game and there will be SPOILERS. Please only watch this if you don't mind the plot being spoiled or aren't planning on playing it yourself.
