I was a little turned off by the demo. As one of the lucky few with a system good enough to run Far Cry well, it just didn't look too great.
Well, I mean, it looked fantastic, but at one point I simply went prone in some bushes and watched as an enemy raninto me and failed to take alarm. I spent three minutes looking through the scope of my rifle hearing a weird noise before I looked around and saw that it was coming from this guy who had spent the last few minutes of his life trampling the grass immediately next to me.
That's pretty stupid. Am I to believe the game is not like this in general? Because as much as everyone is claiming this game is unbelievable, the demo really, really doesn't show it in terms of gameplay and AI.
