My guess would be old enough for someone who is at least a teenager to be nostalgic about it. i say this because I've recently been seeing PS2 era games being called retro in some places which just blows my mind.
I guess it shows my age then that I consider retro to be anything that was made before 3D games became the in gimmick. (which they aren't now but when it was new 3D was as gimmicky as motion controls are now.)
