Yes npcserver is nice
If you don't want to spend time on
writing scripts then you shouldn't start
a playerworld project.
In some ways scripting with npcserver is
even better than with free servers:
if you put a //#CLIENTSIDE in front of
the script it will completely act like in
offline mode, while on the free servers
the npc script-timeouts only run on the
computer of the player who entered the
level first
Only stuff like setlevel, playerrupees++ etc.
is not allowed on client-side so that
hackers have no chance to hack it
