3 of us played last night for a few hours. The autosave lag is pretty hideous, but overall the game seems stable. We used direct IP to connect. The same person who hosts our HOI3 games hosted. Next time we'll try with one of us that has problems hosting HOI3 and see how it does. (we all used to be able to host HOI2 with no problems) We haven't gotten to war yet aside from Italy/Ethiopia... the real test will come in 1941 or so.
Minor issues we noted so far, but none are really MP-related:
-Tech team list resets to the top after choosing a team. (annoying if you have 8 or 10 teams)
-We couldn't figure out how to change resolution for a while... If you have the installer put a shortcut on the desktop, it puts a shortcut directly to the .exe file, not one to the launcher where you can change the resolution.
-I seem to have an issue with the mousewheel scroll.. no matter which way I scroll the wheel, the map zooms out, not in. (lists do the same.. they always scroll down). It might be my mouse, but I haven't had this happen with any other applications. (mouse is a Microsoft wireless laser mouse 5000 if it makes any difference)
