When I was an admin in ~CS~ we tried out most if not all of the mods available at the time to make an 'official mod' for our guildees, I always liked Chronicles of the damned (COTD) which we ended up using, we used WTD 3.5 before that which was ok for a while but ended up bieng abused quite badly in games and from what I remember opened alot of doors up to stackers/game crashers etc COTD with the anti crash and 1.2 was a nice rp and pvp medium, the disciplines were not so "godlike" and it had some nice features. I know not too many guilds used it which was a shame I think
