Probably my favorite video game series growing up:
The only ones I haven't played are the London games and IV. And the only reason why I haven't played London: 1969 is because it didn't work on the computer I had at the time
Also on the topic of GTA, when I was young, I wanted to see GTA 2 in 3D as well as the 3D-era cities (Liberty City, Vice City, and San Andreas) all on one map.
