The Conduit gets 8.6 from IGN
IGN's given The Conduit 8.6/10, which is likely to come as relief to the Wii "hardcore". Snip:
It's not revolutionary, but the Conduit is a great first-person shooter designed just for Wii owners. While the game does not turn the genre upside-down, it is innovative in certain areas -- for example, it features the most customizable, precise and enjoyable controls of any console shooter created, hands down.
The campaign's five-to-eight hours long, apparently. Sounds like it could be a lot worse. Hit the link for the full thing.
