I think Tetris is probably the closest we’ve ever gotten to a “perfect video game”. It has such a tremendous staying power and an interesting learning curve. Playing original GB or NES Tetris is still a blast, but playing newer versions like Tetris Effect and Tetris 99 also have this amazing amount of charm. There are very few games where I think this kind of consistency has existed throughout the franchise’s lifespan.
PlateUp! is a somewhat recent release that I love playing with groups on my steam deck. It’s a multiplayer restaurant sim (think Overcooked) mixed with a roguelite. It doesn’t have as fun unfair chaos as Overcooked and it feels great to play when you have a nice rhythm going.
