Demo didn't impress me either. At the time I couldn't care less about a Story Driven FPS. I had alot going on and no time to really play it. I had just built a new computer and I was newly employed, but I picked the game up at Frys for $10 along with Crysis (also for $10. This was back around mid 08!). At some LAN I installed it and played a few lvls, and BAM! I was hooked. From then on I played the game at night, at lowest settings, on my laptop, and IN bed. Loved every moment.
I let my friend beat crysis lol
