That'd be amazing. I've seldom felt as immersed in a game – I loved the story and the atmosphere. The story of Marathon: Infinity was so mind-bogglingly complex that fans were still discussing and trying to figure it out ten years later. I don't believe there'll be another Marathon game though. However, the fans have done an amazing work keeping the story and universe alive through scenarios (mods/conversions, whatever you call them) such as Rubicon and Eternal.
Oh, and it's a shame Double Aught never managed to release it's game Duality.
I don't get people playing through a computer game with an invincibility code - and doing it over and over. I'm no hardcore gamer (I'm on a Mac Mini dammit!), but I grew up with hard games and enjoyed the challenge. I also believe many of today's games are too easy with their infinite lives and checkpoints/respawn points once every minute. I don't get the same adrenaline kicks anymore since I don't need to be afraid of dying.
Also, jävig means 'partial' or 'biased'.
