InXile Entertainment, the folks who're publishing the game, would have us believe both the DS and Wii version are essential to our survival on this planet, but we know better. According to Siliconera, each installment has its own features to lure you in.
For one, the DS game has the incredibly intuitive and easy-to-use touch-screen, which switches between drawing controls and playing controls on the fly, where the Wii version situates any menu buttons it has in the corners of the screen. Also, the Wii version will feature Wi-Fi support, whereas the DS installment doesn't look like it does. The DS title is pretty portable (natch), while the Wii version is not (sure, you can lug the game and case around, but you can't play it).
What about you all? DS version? Wii version? Couldn't care less about either version?
