Yar, i concur that the game is a little more up to date in terms of physics engine, thats a given. What i meant is both games are very similar in style (as apposed to something like Unreal tournament), which is very different style of FPS.
I welcome any new game provided it can be quickly installed on a bunch of pcs... setup time is very important
If you can encourage enough members to install it, then at the next LAN party i will host a server of CSS.
Personally, I would like to play more Unreal Tournament 2004, but people dont have it installed yet... mayhap i will ask people to start transfering the files as soon as they are connected to the network. Also some fun Starcraft is always nice....
