I want to get my son a Pokémon game for his game boy for his birthday. I was checking out the used game store, and they have a few different ones, but they are kind of pricey for used games (yes, I’m lame and know nothing about Pokémon). If I can only afford to get him one, what color is the best? I think they had red, green, maybe blue and gold? They also had some that were the normal gray color but were way cheaper. He just has the old timey game boy advance. Thanks for your help, I am sure my son will appreciate it. I think I was 16 when it came out here, and I cared more about boys than games then so I'm pretty clueless. :)
