You're either totally serious or totally jacking around. This looked like it was going to be an awesome retelling of the OT and now it seems that it was nothing more than a distraction for you.
So, how fun is it to get through endless levels of Doom 3 doing the same thing over and over again? If you're going to play a tech demo, at least play something like Lost Coast that actually features new tech and different things happening throughout the game. It may only last 15 mins, but it's an awesome 15 mins.
EDIT: Looks like I posted long after your reply. I do hope you continue this. It's a lot of fun to see it.
