Metal Gear Solid V is set in 1984 and originally, series creator Hideo Kojima wanted the game to really have that 80s feel.
According to what the MGS guru said on Twitter , MGSV was going to include an 80s filter screen effect, as inspired by Ron Howard's film, "Rush." The latter is set in the 70s and features the texture and style indicative of that decade.
So, Kojima and Co. thought about using an 80s filter in MGSV, but it turned out to be "too heavy" and slowed down the performance of the game. "So we had to take it out," finished the designer. That's too bad, though, 'cuz it could've been a super cool addition. However, I'm not sure the young'uns would've wanted it; they don't care about retro the same way we didn't care about old-fashioned stuff when we were kids. Nostalgia doesn't logically exist in the early years, you know?
Still, I at least wanted to see it.
