I would love to see both,, but we just dont have the resources.
SK is a 1.6 thing, the physic make the SK’s in source lame. If anything we have a large community allready here that play on other 24/7 SK 1.6 servers. so if we even get a SK server it will most likely go 1.6 as our campus community has been requesting for years now…

I would love to see a GG:S server, i’v had alot of fun building and weeking the 1.6 gg server, however i rarely/never got input or sudjestions and left it be… now its nearly dead. I wouldent have a problem replacing GG1.6 with GGS or have both, but again dont think we have resources…. 
PS: if you ever join a 24/7 SK server you will see how good those guys are, thats all they EVER play. but its still phun loosing
PSS: when ever TF2 comes out more than likely it will replace the dod:s server.
