online play??

[Spledge]

I've seen instances where I consistently send two files; CMT and DAT, but then receive two visible files in return but then discover varying numbers of "invisible" files picked up by a security/anti-virus program from an opponent also as part of the packet.

Regards, I still have interest in my original scenario, playing SP on a server where opponents don't exchange files, they play the game in perhaps the hot-seat mode.

Do these environments exist in our community?

Thanks.
