This game is the antithesis to Void Stranger. Both titles are essentially modern takes on the "retro" genre, and UFO 50 attempts to make the "treasure hunting" of thrift store finds into a game, while VS just aims to make one really good game.
The majority of the titles in UFO 50 are shit. Some of them are alright, but all of the good ones could've used longer in the oven, they are mostly half baked. The standout title is Mini and Max for me, and I wish there was more of it. In UFO 50 you play games you don't really enjoy for the sake of the cheevos, and while this occasionally leads to some fun you weren't expecting to have, a lot of it is just a slog. Good games don't need to trick you into playing them, they're just good. I gave up on UFO 50 after probably around 40 hours, with maybe half the games cherried, because I had mostly ran out of games I enjoyed playing. VS, lasted 60 hours and I enjoyed the majority of that time, unprompted by cheevo hunting.
