PlayStation 2

Sea Monsters: A Prehistoric Adventure

Even if you share the same sort of fascination with ancient aquatic fauna that I do, there's really no reason to throw down cash for either version of the game. Yes, the Wii version makes the PS2 one look like a sick joke, but a pile of crap that's twice as nice as the pile sitting next to it is, in the end, still a pile of crap. It might be worth a rental, tops, but avoid actually paying money to own it.
