Of course, no problem at all.  I'd suggest you watch some gameplay footage or something, just to get an idea of the environment and whatnot, but it would be stupid for me to say no to non S.T.A.L.K.E.R. players.

Yeah, advanced doesn't get a lot of pull for some reason.  Speaking of which, I should probably put up a section for post guidelines.

Also, just FYI, I'm changing the age cap from 50 to 65, because I realized that it isn't necessary for this story arc.  It was relevant in my old one, but not this one.
