That *said*, now that we're getting closer to a point where there'll be little-to-no separation between single-player and multiplayer, and with the mod support incoming Soon™ for MC, I'm looking forward to the day I can start adding in some of the stuff from
Mo'Creatures (and maybe a few things from
More Creeps & Weirdos [want those damn guinea pigs]). Long as I can leave some mobs out, tweak the ones I wanna tweak, and alter overall spawn rate, then that's probably when you'll see me turn mobs back on in some fashion. =D
