Aside from an emphasis on story, Mr. Häkkinen says that weather effects will play a role in gameplay, specifically noting (by way of a strange sounding Google translation from Norwegian), "Everything in the game can be influenced by the weather. If you are running the car, run conditions will be worse by heavy rain, than if the weather was good ... the weather is dynamic, since it will influence how you play the game."
Furthermore, Mr. Häkkinen tells Gamer.no that, "Lighting is very important in the game, and this is a unique item that really has not been used in the game before on the way we do it." The obvious comparison here would be to last year's conceptually strong Alone in the Dark -- here's hoping Remedy can deliver on the lighting concept where Alone in the Dark more or less failed.
So, we officially still know little-to-nothing! We'll keep an eye out for information at E3 2009 in June, but, ya know, we're not holding our breath or anything.
