Building rules have changed. Creation tab is now split into four categories. Waypoint system superior to all I've experienced. Hotkeys are easy to remember. Very well balanced.
Patches are small downloads.
Version 1.003 patch is only 1.26 megs while the official mappacks are around 250 k's each. Autoupdate program is a nice addition. The collector's includes a DVD with in-game cinematics of all missions. Behind the scenes photos, and movies on Kari Wuhrer and Kier. Also includes artwork, and the not politically correct rejects.
