Collect SNES or N64 or Gameboy??

[Futbol 04]

Hey there. I have a passion for all 3 systems and love collecting. But which one should i focus more on? I would like to complete one of them. I dont care how big the amount of games for the system is. Just want one but I cant decide. So far Gameboy is winning because not as many people collect for that. Then follows N64 with amazing games such as goldeneye, perfect dark, mario, etc. SNES has had maybe 1 or 2 votes. I don't know why. So if you could help me out and give me a reason what to collect I'd really appreciate it
