What you say is true Wolfie456. Many people on Friendcodes are mainly on the MArio, Smash, Zelda, and Pokemon franchises. I think the reason for this is because most members on Friendcodes are younger and haven't experienced or been through the SNES or Nintendo 64 saga.
When I was like 4 I just started in on the Nintendo 64. I never got to experience the SNES and NES stage, and I'm really sad I missed it. Some people on Friendcodes jsut haven't had much experience with games outside of Zelda, MArio, Samus, etc. That is the main reason why people don't make threads or talk much about Mario, Zelda, Pokemon, etc.
