I should know this, but don't. #2 son is getting a laptop this week. We share interest in several games, but have never played each other before.

He's coming over, with his new laptop, to have a CallOfDuty2 duel with the old man.

Q: Must we go to the 'net to play, or can we simply connect machine-to-machine via ethernet ports?

The last time I actually performed this operation was 1985 with Burroughs 360's, using standard army WD-1 commo wire, LoL.
