So, basically, Deus Ex is a Ghost in the Shell game. I mean, you could transplant the setting, characters, and most of the story elements to Japan, and it’s Ghost in the Shell.

Okay that’s probably simplifying it a bit, but I can see that Deus Ex is pretty much the quintessential Cyberpunk video game. It and GitS probably worked off of many of the same influences like Neuromancer for instance. Whatever the case is, it’s unlikely that this game wasn’t at least slightly influenced by GitS.
