I don't think people should just have the right to make pirated or counterfit games or products in general just because they want to, just wanting something isn't enough of a valid reason. Especially when so many people are just making these to profit on. Someone was making copies of Stadium Events awhile back.
I've run into enough parents who bought pirated GBA games that they thought were legit because they were sold used at Gamestop. Not everyone who buys these things knows what to look for, plenty of people buy these as gifts for others. At the very least they shouldn't look near identical to legit versions.
