I think it depends on your personality. Personally, i'd love to go walking in a place like Tokyo, NYC or San Francisco, just to explore and do my own thing. I love walking in the woods by myself and seeing nature up close. Open worlds are just about exploration which is just something that we have within us as people.
There's an open-world racing game that i might get later this year, that would be sweet. I also hope that if MGS 6 is made, that it will be an open world game. GTA is just as nice.
