Same for me too! We have too much in common. :P

I still hold every Halo game to this demo's standard. It has that iconic 30 Seconds of Fun but also 9 Minutes of Wonder. These little set pieces like the field medical unit, the chat between the Marine gunners, the comms with the Longsword section, etc. all bring so much atmosphere into the mix. It gave you the sense that you were really a soldier in a vicious conflict and not some cookie cutter action hero battling the enemy of the day.
