These are probably the most well known fake Pokemon games, since some sites actually reported these as legit games. The confusing part is that an official version of Pokemon Diamond has actually been released by Nintendo for the Nintendo DS. The fake game used to be prevalent on eBay and Google, but it has recently been cleaned up with the release of the official version of Pokemon Diamond.
When you boot up both games for the first time, you are forced to endure a 30-minute intro sequence of bad English and confusing dialogue; you'll wish you could get those 30 minutes of your life back! The game is a standard RPG that takes place inside of a tree with a ringing phone underneath it; nothing out of the ordinary, I mean who doesn't have a phone under their tree? The weird thing about this game is that not once do they use the term Pokemon; instead they say "electric monsters world". At first I thought it was due to copyright issues, but they put "Pokemon" on the front of the box, so I think Nintendo is pretty ticked off as it is.
When the game finally begins, it plays a lot like a normal Pokemon game with a couple major differences. Just like a regular Pokemon game, your character travels through grass to encounter wild creatures, but when you defeat one, it becomes yours; there is no such thing as Pokeballs in this game. Once you have encountered a creature, these 'electric monsters' will call you up with pointless comments, like asking you if you like curry, which for the record I don't. I've never actually tried it; actually I don't even know what it is. I think people from India like it or was it Saudi Arabia... Well speaking of copyright material, I'm going on about another topic in the middle of a completely different thought just like they do on Family Guy. Anyway, the sad thing about these games is that the box art keeps changing; just stay away from these games, which are sold by the bushel on eBay to unsuspecting to parents and children. Why? Because the game is boring, the graphics are awful and it plays nothing like a Pokemon game, so beware!
Pokemon Diamond and Jade were translated from the Japanese games Keitai Denjuu Telefang: Power Version and Keitai Denjuu Telefang: Speed Version. The sad thing is, all the bootleggers changed were the title screen and the sub-standard translation; everything else in Diamond and Jade is the same as these Japanese games (which apparently had a GBA sequel).
