The first sequel in the long-running Metal Gear series originally launched in 1990, but Hideo Kojima says it wasn't supposed to be that way - it was delayed because he and his dev team had to go help out on an RPG spin-off of one of his earlier games.
Don't confuse Metal Gear 2 for Metal Gear Solid 2 here - we're talking about the 1990 MSX game that was released only in Japan rather than the 2001 PS2 classic. At this point, Kojima had directed a bonafide hit in the original Metal Gear, but he didn't have the megastar reputation he enjoys today. After Metal Gear, Kojima led development on Snatcher - a narrative-driven adventure game dripping in noirish, cyberpunk vibes.
