Free-riding is less common at LAN-parties than on P2P networks.
30
Free Riding
Free riding on P2P networks: Connect to the network without sharing any files.
Free riding at Lan-Parties: Download at least one file while sharing none.
We care because the value of a sharing network goes up the more content is being shared.

ConclusionWhile Lan-Parties officially caters to gamers, there is a lot of sharing going on.
Everybody shares.
There is less free-riding at the Lan-Parties than on P2P networks.
Features of Lan-Party networks promotes sharing of larger files.
