Fakes: Pokemon Diamond and Pokemon Jade
A game titled "Pokemon Diamond" and "Pokemon Jade" showed up on auction site Ebay back in 2001. Pokemon Diamond and Pokemon Jade are not real Pokemon games. The games claim to be a Pokemon game, however, this is not true. Doing such thing is obviously illegal.
Several pages of these false goods could be found at Ebay back during the time when it was first discovered. Fortunately, it's much more rare now, although the item does appear every now and then on Ebay.
So be aware of these fake goods, this applies to buying anything online.
When I say "fakes", I mean that these are not real Pokemon games. It doesn't mean it doesn't exist, it does.
Not to be confused with Pokemon Diamond and Pokemon Pearl
Don't confuse this with the titles Pokemon Diamond and Pokemon Pearl for the Nintendo DS, which was announced years after this incident.
