CTF would actually be pretty fun and popular if done RIGHT. Old CTF was barely used, but it could be improved and maybe then it'd pick up popularity.
Hows about CTF with
No Bombs, Arrows. ONLY the sword and glove buttons should be enabled.
No fee, no prize, just for fun
Multiple locations with different maps for each one.
Guild CTF perhaps?
.... and maybe THEN you'll have people playing CTF and raving all about it.
