Are there any games you don't play as it was intended to be played? If so, what game and how?

I know I remember seeing some people talk about how nice some of the environments in Hitman were, and that they'd just walk around as a tourist from time to time, treating it like a walking simulator/virtual tourism thing instead of the stealth assassination game it is. Curious about other things like that, where you play a game totally differently than it was meant to be played.
