I use no CD checks for two reasons:
No CD check.. which lags the game and so me and my wife can play over the network... Yes I got lucky and married a wife that like network gaming to...
Maybe if they would limit the CD checks to once every 30 mins.. I seldom play a game less than 30 mins.. It's usually hours.
Or... make it standard to put two CD's in every box for the ones that are networkable. That won't cost them more than 5 cents more on there side..
or make an option when a network game is started to chose wheather you want a cd check directly to the CD or over the network to the one with the cd. That way you could have several people on different computers in the same house.... They could put the limit at 6..10..ect... and make it only workable in that manner over a home network and not the internet..
