Just beat The Legend of Zelda, The Ocarina of Time. I downloaded it a few weeks ago on the Virtual Console and it’s kept me busy for a while. This game is considered by many to the the greatest video game ever made.
Despite being originally released in 1998 for the Nintendo 64, this game still holds up really well by even today’s standards. The simple blocky textured 3-D graphics are dated, but the gameplay and story still hold up, if not exceeds that of today’s great games. A great game.
