38. Beneath a Steel Sky (PC)
I played BaSS when it was made available as freeware just under ten years ago (to the best of my knowledge, it still is, should you feel like checking it out), it's a Sci-fi point and click adventure game, first released in 1994 when that kind of thing was still pretty popular. Given that it is set in a dystopian future in a world ravaged by pollution and nuclear fallout, it holds up fairly well and keeps that futuristic feel that some fiction can struggle with over time. The game centres around Robert Foster, and his attempt to uncover who he is and what is going on in Union City, with the help of his robot sidekick whose personality can be transferred into a variety of machines to assist as required.
Number 37 isn't GTA, but it's something similar.
