Ahh, the old Duke. Didn't offer much beyond the more atmospheric Doom from where I was standing but still, it was fun seeing people teetering on the edge of insanity and despair - and after a while, admittedly (elapsing time is a remarkable thing), you start giving up on your criticism and sarcasm and whatnot, you drop the defenses and actually start rooting for 3D Realms to get it finally done.
Is probably the reason why even Yahtzee succumbed and mused and jollied about what could have been. Oops, sorry, why even Yahtzee succumbed and lauded the greatest game ever produced by mankind, showering it with the highest accolades and praise at his disposal. There's no escape from the Duke. When it's done.
