What is "nestalgia"

NEStalgia is an indie video game, for Microsoft Windows operating systems, created by Silk Games. Described by developers as " Dragon Warrior 3 meets World of Warcraft", NEStalgia is a modern online role-playing game made to look and play like a classic role-playing video game from the 8-bit console era. NEStalgia was in development for 2 years before publicly launching on February 23, 2011. In the time following the public release the game was almost completely overhauled and remade, leading to its launch on Steam on April 15, 2014.
