1994 always gets me too. It feels like they are more a late 90s thing.
Which means that we're really talking about hardware from 91-93, right? I.e. if launch was 94 then they were designing in 91-93ish.
PS2 didn't come out until 2000. Most of the games I remember are from later too.
They didn't launch outside of Japan until late 1995, so most people got one in '96.
