>>34660745Go to ebay and learn how to spot them. It very easy. If you don't trust yourself to spot a fake go to a reputable seller. Gamestop has surprisingly good prices except they are never in stock. I can't personally vouch for the quality.
My advice is to put in the time and don't cheap out. That's what I did. I have all 5 Gen 3 games, all legit. I don't know about Gens 1 and 2.
