Creatures is all that. What strikes at you right away are the fun creature creations . All types of land mammals, herbivores, and water types are up in your enemies face as you shout out their names if they want to battle you. The simple design that allows any animal to be combined gives the game it's own style, sort of like napkin drawings or doodles for fun. With 96 cards giving you multiple messed up animals the game doesn't tire easily.
The games easy enough and fast to learn to play. Rules are simple build animals with the 7 cards your dealt, attack each other, if your animal is more powerful based on the combined points it's made up of you destroy the other animal. If your the winner you also get to scavenge from the beaten animal. Take one card, sort of like taking the DNA away from a corpse via Bioshock, just not as disgusting and make the card into a new animal. Some tricks and special gimmicks like your animal being poisonous or if the other player doesn't have an animal to play will change what happens, but the rules will get you through it. The game can go pretty fast, and the best part might be attacking the same opponent after another player just has.

Finally, for the parent's it's for ages eight and up and can be played with up to six people or as little as two for a dog fight or maybe a Bum-Ga-Pine fight (Bumblebee, Kangaroo, Porcupine).
Just grab the game here and maybe the magnets and t-shirts.
The only thing I could think of is if somehow a Pokemon version could come out with maybe more enhanced rules for older players, I'd love to see a Char-tur-chu (Charmander, Squirtle, Pikachu)
