This has been bothering me for honestly the longest time. I want to buy a Pokemon game, but I can't figure out which one to get - there are at least 10 different versions for gameboy advance alone, and approximately 12 different versions specifically for the DS. I guess I'll go with either HeartGold or SoulSilver, but I'm feeling a bit on the nostalgic side. Would it be worth getting Emerald/Leaf Green or Fire/Ruby Red as well?
