It's not hard to believe in a literal sense, but it does make me feel very old. I got metroid for the NES when it was new. I was in my early teens. 30 freakin' years. 3 decades. Jesus.
It would be hilarious if Nintendo released an unaltered version of Federation Force from what it was like when they showed it at E3 and put some kind of anniersary stamp on it.
