I'm kinda late to the party(considering Napoleon Total War was just released), but I just purchased Empire Total War, along with all the addons. I would of purchased it sooner, but when I had first got my laptop and tried the demo it caused my laptop to lock up and crash.
But after getting Crysis to work on High, much thanks to Feuer Frei!
. I decided to try it again. I re downloaded the demo and let the game set itself to Very High. Loaded up the one battle and started playing. At first I noticed it was a little sluggish moving the camera, but it worked itself out. The only other lag I experienced was once after an American unit had all fired there guns, I viewed it up close, and trying to rotate the camera was a bit sluggish. I'm currently downloading the main game now, and will soon be playing.
To help pass the time and set the mood, I rented The Patriot and Master and Commander in Blu-ray.
Edit: Just realized I spelled Bought wrong in the title.
