Crysis has to be the most beautufily realistic game out ever. Unfortunately, I cannot even consider running it as I sure as hell am not going to settle for low settings and sure as hell can't afford a $5000+ new computer (being unemployed) to run it on very high settings.
Soooo, I scour the YouTubes for videos of what I could be getting IF I decided to sell my first born. The level editor rocks, by the way...I can't wait to check it out in a year or two. :P
Check out the video above that someone made to show off the really neato physics that the engine can do. Take note, I believe the entire thing was RENDERED at 8spf (seconds per frame), so its not like this is real time...but it's still cool beans.
The video below is just a soothing look and feel for being on the ocean. Ah I wish I could build levels in this engine...sigh.
