Well what screwed us up is that the servers weren’t touched or screwed with at all and yet some were magically different between the last LAN and this one. I could very easily pass the blame on this one but won’t for fear of sounding redundant.
The install issue is complex. Over half the computers that are brought don’t have enough power to install a large game like CoD4 while playing another game and the big problem with Left4Dead was that people didn’t want to have to play TF2 on a seperate account, thus losing their achievements, while installing it. The Left4Dead issue is very easily fixed, the CoD4 not so much.
