tinyE: I'd heard mixed reviews ...
Mixed? the absolute bastards - They don't know what they are talking about :) From Commander Keen all the way up to Arkham City, Blade Runner wipes the floor with any game when it comes to atmosphere. It's not even that much of a game if I'm perfectly honest : more of a noir cinematic experience (by which I don't mean a lot of cutscenes) in a cyberpunk universe with saxaphone mood music from the film. Dammit but I've got to play this game again!
Sorry :P I'm a huuuge fanboy of the film and game - remember, Philip K Dick saw some of the pre-release footage of the world they envisaged for Blade Runner, and he approved wholeheartedly.
Oh and if you do want to play it, play it at night with a glass of wine/martini or whatever :P
