Not sure how to ask this... hmm, I'm not sure if I understood this correctly but there seems to be a limit on number of networking connections or players with this "free" version?
I mean, is it possible to connect or use external modules or does this "free" engine has no possibility of having an unlimited networking? Say I want 1000 or more players?
EDIT : I mean this : "Client-server model support for up to 64 players." ( http://udk.com/features-networking.html )
