Did somebody say Geist? Yeah this game is going to be sweet. I played a ton of it at E3. It's got some great ideas. It's much more of a first person adventure than a first person shoother. In the most recent level at E3 2004, the first half of the demo was pretty much all adventure and the second half was a shooter. There are tons of little detials, for example when you possess the dog your vision changes. It gets a slight fish-eye effect and the coloring changes to black and white with yellow mixed in, which is how a dog really sees. nSpace has put a lot of detail into this game. It reminds me a lot of all the detail Silicon Knights put into Eternal Darkness.
The multiplayer is lots of fun. The possession aspects of the game really freshen things up.
Also, it doesn't look like ass. Part of the problem was the monitors Nintendo was using at E3 this year.
