[General Discussion] Best Pokemon Game

I would say simply get the GBA ones. Maybe Emerald/Sapphire/Ruby and Leaf Green/Fire Red (one of each, cause they are the same game just with different Pokemon). There are some pokemon that can only be gotten through Colosseum, but that game is so slow that you will be bored to tears. I've actually beaten it, but it takes a while. There is that puzzle one that I hear about...so if you like puzzles, maybe you could give that one a go.

Gold/Silver/Crystal are easily the best ones, but they're pretty dated by today's standards, so I would go with the GBA ones. It's up to you though.

And if anything, you could always go to some review site to see if your interest spikes. Or something.

For your edit: You can play the GB/GBC ones only on your GBA, not the DS.

Jam it back in, in the dark.

No. I don't believe you can transfer from the GB to the GBA (even battles). I was trying to trade my Gold pokemon to my Sapphire, but its not possible. =(

I do have to say that some of the Pokemon Colosseum music is pretty good though. If your cousin has it, you should check it out.

There's nowhere I can't reach.
