99blacksesport, that list is inaccurate. I have just about all the games on that list(Don't ask). I have played a few of them since I had the SP2 Beta and I no problems here.

Microsoft stated that most of the problems are associated with the new built-in Windows firewall, where users must approve programs that attempt to make Internet connections. However, some programs use data pages that the firewall automatically blocks, as they are common attack routes for hackers. A work-around is built into the firewall software, as well as the ability for advanced users to simply turn it off.
I have the firewall off. So, that is why I am having no problems.
