"The Horror... THEEE HORRRORRR".
seriously, as long as i can run a LAN server with my CS 1.5, i would not care less. As i am spoiled with STEAM already. But i can imagine that there are A LOT of people that are going on STEAM, NOT BEING HAPPY... or they won't use STEAM at all.
Perhaps some smart dude finds a way to simulate a WON server. I know this is already done for NFSU. You can create your own lan games there , you simply fool the game that you are on th einternet and you run that 'simulated internet server which is actually a lan server'... thingy
