I wouldn't exactly use Metal gear as an example of a good videogame narrative. It is borderline ridiculous and I doubt very many people found the extensive use of cutscenes in MGS4 "fun" or were many people grabbed and pulled in by the cash grab that is ground zeroes. When I think of good videogame narratives I think of halo, TLOU and Half Life and two of them are FPS games. They have good stories that draw you in but don't get bogged down in cutscenes and story as MGS often does and keep the pace and fun throughout the entire experience without it slowing to a crawl.
