[Newworlds]

I'm not familiar with any good MUDs that don't have some kind of "auto" combat. It is the best way to actually keep things active in an online game. Turn style combat tends to become so drawn out (someone leaves to lunch during their turn, times out, etc) it bogs down interaction.

However if you are looking for games that have different types (more interactive types) of combat, I know there are two or three that get into enhanced combat with shield positioning, distancing, position placement, etc, that can make combat much more interactive. The game that comes to mind first is Dragon Realms. God Wars is also this way, I believe, but it is a player vs. player style game.

For huge worlds and lots of quests, albeit, hard to find people because the world is so big, you might try Materia Magica.

I'm sure there are more. Good Luck!
