UFO 50 has been my favorite game (collection) of the year and I haven't even played all of the games in it yet! It's just super exciting discovering a bunch of games without seeing a whole lot about each one yet, without knowing every little bit about all the mechanics or having everything tutorialized to hell. Seeing mechanics and artwork get more complex as the fictional history of a game console unfolds. It's an incredibly impressive and super exciting work, and loads of fun to play.
Not sure if this fits the bill perfectly, but my most proud creation in a game definitely is bringing my board game Trivia Throne to Tabletop Simulator (find it on the Steam Workshop)!
