I played the demo of this game and it was good enough that I had to purchase it off Steam this weekend. With the patches out (over 800Mbs) it is a really fun game. Titan Quest/Diablo/Sacred hybrid. Very nice graphics and gameplay. Looking for peeps to co-op online with. <--------------------------> To Update the First Post. Ok I can confirm that Sacred is working 100% on Closed Net with windows 7 64bit ultimate. I would imagine a lot of your are using the Beta's for windows 7...I was. There seems to be a big difference between then beta releases and the public release. What I did to play sacred. Installed Windows 7 64bit Browse to this folder (if you are using Steam) C:\Program Files (x86)\Steam\steamapps\common\sacred 2\system Apply compatibility mode to sacred2.exe and s2gs.exe Choose Windows XP SP3 and check run as administrator IF you are using Nvidia based cards disable Physics at the adpater level. Also be sure to disable Physics in the game. Thats it. After that I am able to play on closed net servers. Open net servers I constantly get error 10 disconnects...UNLESS the host is on Windows XP then I can play open net as well.
