I still enjoyed V overall, the initial MGSV Ground Zeroes Mission is a smaller open World that does work well, especially for doing missions many different ways, some of the MGSV Phantom Pain open World parts don't work as well as they're just too big, still some good mission though.
Has a super indulgent opening as well from Kojima, takes a while to do near anything at all like playing a game but picks up a lot. I did enjoy some of the collecting and base building elements too.
As mentioned especially 3 is an amazing game, but many are worth playing in series, I enjoyed the Nes version and Gameboy Ghost Babel, and the original MSX games. Well worth picking up the HD collections for 360 or PS3 if you can play via backwards compatibility, they include 2, 3 and Peace Walker.
