No particular order but mine would be (I went with a top 10 list since I just couldn’t narrow it down further):

1. Factorio
2. Portal 2
3. Arma 3
4. Bastion
5. LA Noire
6. Red Dead Redemption 2
7. Halo CE
8. Stationeers
9. Any of the Metro games
10. Tetris

Only time I’ve ever had an “electronic” device checked like that was at an airport in Europe about 15 years ago (if memory serves me right, I think it was CDG in France). I had a DSLR with a couple extra lenses and they asked me to turn on the camera and take a picture with each lense attached. They also asked to view through the viewfinder with each.
