I thought it was widely known that Sega can't market their products for s**t.
Now as someone who has played Conduit I would like to say that the game is not bad, I would say it falls somewhere between mediocre to good. But thats the problem, its just another run of the mill shooter which doesn't do anything radically new, and that really is kicking yourself in the groin because there are so many high profile shooters in this gen already: Halo, COD, Battlefield, KZ3, etc, etc and some of these also have very precise and better motion controls with the advent of move, so the Wii's only strong point is now no longer its strong point. One may question why Conduit is being compared with the above franchises, but if we look closely we will see that the people who buy conduit are the core gamers who also have one of the other HD consoles (casuals are not interested in FPS for the most part), so they have no reason to invest in a game that is inferior in every way in terms of graphics, controls (motion or not), story, online, etc.
Basically, in an oversaturated genre where there are a LOT of quality games available, you really can't compete with a mediocre, or even "good" title, you just have to be exceptional, which conduit 2 was not.
