Yes you could definately make a single player version of EQ
and as long as you had a stable platform built up , if you had
the time and the will you could make it just how you wanted it. You should go for it man ! the only problem you'll have is getting a correctly patched version of EQ (pre 5/11) if you're not sure what version you have or what to do , search the forums for EQ version check. And you should be good to go with some of the great new tutorials out !
