Outside of Nintendo, not many developers seem to understand the power of the Wii. In fact, most of the system's games last year were nothing more than greedy afterthoughts - titles clearly designed for another console, but then married clumsily to some motion sensitive controls and re-released to sell more copies.
One of the rare exceptions to that trend was Rayman Raving Rabbids, a non-Nintendo party game so bizarre and so interactive that it could only work on the Wii. Indeed, when Ubisoft tried to port it to other platforms, the resulting products weren't nearly as appealing. So for the sequel, Rayman Raving Rabbids 2, they're concentrating solely on the Wii and on taking even better advantage of its unique strengths.
