I'm so young but. I got consoles late. I got a N64 in 2003 along with a PS2 and a GC. I played the N64 a lot first and even though PS2 and N64 are close for me.
It has to go to N64. Even though on SNES I played FFIV and A Link to the Past like crazy all my memories are on N64 because I played it the most first!
