* Fallout New Vegas - Explore the post-apocalyptic wasteland of the Mojave. Many ways to play the game. Worth playing and re-playing.
* Keberal Space Program - Build your own rockets and try to get them into space. There is so much you can do with this game via mods. Mechjeb is a must as it makes it much easier to get your ship where you want to go.
* Sim City 4 - There's really no substitute for the classic. Cities Skylines is ok and I might try it again on the Deck. It seems to be broken on the switch (gameplay falls apart at 30k pop).
