Played two MP games last night and it was awesome. SDC and IC you guys rock. I only had an hour but found a couple of small things. When you are setting up a game the chat text only allows you to type a few characters at a time. In the main lobby it seems to allow you to type a lot more text at once.
Also I noticed that the main lobby sees all the conversations from games that are being setup. Not sure if that was intended or not. I guess it is nice talking to the guys in the lobby while you wait to get your game going.
Both games we had random horrible freeze ups. The first game I think someone completely lagged out and everything locked up. The second game was much larger and we would have random lock ups. Not sure if that was related to people's internet connection or not. After about a half hour of playing we lagged out of that game as well because it completely froze up.
Hope this helps a little.
