So much like everyone else on the planet, i've been playing the hell out of TPP (finished Chapter 1, yet gonna need to take a break from it since I have a full week of college studies ugh! ) and as someone who has played through MGS1, MGS2, MGS3, MGS4 and Peace Walker... I am left wondering if I missed anything by not playing through Portable Ops. I know it's not listed on Kojima's MGS timeline, but is it worth going back and playing or should I just load up one of those YouTube vids with all of the story beats and cut-scenes or should I just ignore it entirely?
