Seconded. That's why it's fan fiction, it's the things everyone thinks they want to see, gotta spell it all out, gotta bring all the characters together for no reason, gotta make Meryl marry Johnny, gotta have Snake not die at the end, gotta have Big Boss show up one last time, oh look Zero is also there for some reason... you get the idea. People eat it up and it fills them up but it leaves nothing to the imagination. And yeah, that comic that's so "brilliant" just makes more explicit all the things the ending as-is hints at subtly and much more cleverly (the "Operation Intrude N313" tape, SO GOOD). Undercutting that with a last-minute Codec call to the real Big Boss would've been MGS 4-level pandering but I guess some people really like that.
