The trailer is for people who HAVE been following the game to see its progress. Marketing to those who don't know much about it will begin when Sega starts up the pre-launch campaign. Right now those who have been following it have been primarily interested in how the visuals are improving, you may not care about that aspect but that is what many who are anticipating the game are focused on. They've talked quite a bit about the All Seeing Eye and how they've been working hard to modify it to make for fun exploration in the game along with puzzle solving.
Also there is NOTHING I mean NOTHING wrong with using IGN to get the game out to the public, it is a big thank you to them for getting the game noticed in the first place. The Conduit wasn't being ignored by publishers because it was "generic" it was ignored because publishers felt the Wii audience would not buy a more traditional game like it. Thanks to IGN the game got noticed, and THROUGH IGN people who are interested in the Conduit have been having unprecedented access to help influence the game.
There is a reason why they've focused on the visuals, because that is what the majority of people who've been supporting this game want to see. It SHOULD NOT be indictment of what the final product will be like.
Halo and Goldeneye's multiplayer is legendary. It'd be hard for any game to measure up to that level of hype and nostalgia, and frankly even Halo had things like vehicles and whatnot to spice up multiplayer. Have we seen that with The Conduit?
Cod4 is widely regarded as having one of the best multiplayer modes right now and it does not allow you to ride in vehicles. Vehicles are a gimmick if they aren't used properly, you can have a compelling experience without them.
And if you read my post correctly, you'd have seen that I never called it a First Person Shooter. I called it a First Person game, and it happens to feature (apparently bad) FPS shooting segments. But my argument stands: that game took a stale genre and carved out its own unique niche by pursuing First Person platforming, and whether you like it or not you can't say it isn't its own game. Bioshock took the stale FPS genre and carved out its own niche by pursuing layered storytelling and a unique world with its own ethical standards, and whether you like it or not you can't say it isn't its own game. Now, is The Conduit its own game?
Still it is a poor comparison. It is like comparing Metroid Prime to Halo and indicting Halo for not being as innovative. Not much I can say about Bioshock because I think it was a ground breaking title, one that only comes around once every several years.
