So, the Conduit is pretty awesome. Obviously peeps with the higher powered consoles already have their own version of this (say, Resistance for PS3 and Halo for X Box) but the Wii definitely needed a game like this. The single player is fun, blending the run, stop and shoot formula with some good exploration and hidden secrets and fantastic and very customizable controls. But the online multiplayer is really what it's about- no lag, very easy to use (unfortunately, to friend someone, you do need their friend code... grr), a ranking system, and just some damned fun levels and weapons. All together, a much better online experience than Medal of Honour Heroes 2, another great Wii FPS, since the levels in that game were all to huge for anything less than a 24 player game and rewarded sniping too much for people who don't have 24 hours a day to spend videogaming.
So, Conduit= +++. If you only have a Wii and like FPSes, get it. If you have other systems, still really like FPSes with Wii controls, and have some cash to throw around, hey, pick up a copy too.
