http://www.pakistan.tv/videos-cricket-infected-with-parasitic-worm-commits-%5BD7r1S6-op8E%5D.cfm Basically its a parasite that lives inside various insects, when it reaches maturity, it somehow (science currently does not know how) compels the insect to kill itself in a body of water so the parasite may leave the host. You are now wondering what would happen if these evolved to infect humans.

It extracts blood through the claws on its front, causing the tongue to atrophy from lack of blood. The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub. The fish is able to use the parasite just like a normal tongue. It appears that the parasite does not cause any other damage to the host fish. http://en.wikipedia.org/wiki/Cymothoa_exigua **** YOU NATURE! **** YOU!
I don't doubt that it apeals to the casual audience. And I support them having fun with it. I won't buy it until it's implemented practically into games that are for a hardcore audience. I don't see that happening anytime soon, the Wii has been out for years and it still pushes gimmicky games out.
