The Forgotten City is absolutely brilliant. It offers an exploration of mythology, philosophy, religion, morality, time loops, fate, and more. The game is populated by wonderful characters and features many branching, intertwined storylines that are a joy to slowly see revealed. There are so many ways things can go based on your decisions, and the dialogue is among the best written in a game I've ever played (with superb voice acting, too!), worthy of spending the time to listen to every line. It may be a "mod", but it's arguably as good as the game it was made from and such a uniquely memorable experience that it is my personal game of the year for 2021.
