How many dates in your life do you remember?

Well, I do remember Alana's birthday - the day I first played in Sloth. As well as the day she inmorted. I am not an imm right now, but it has nothing to do with my appreciation of the MUD.

I've visited hundreds of MUDs but found very few where I would have gotten hooked. Original, multiclass and completely free? That's a lot to ask for. The world of Sloth is completely original (it's a DIKU, but no DIKU areas); you create your char selecting 4 starting classes out of 8 possible ones. Everyone who grows enough gets a fifth class, Avatar: your avatar powers will be different depending on what your first four classes are.

It is not a roleplaying MUD: some players roleplay a lot, but it's their own style of play, not something where imms try to enforce their notions of 'proper' roles.

A lot of the code and areas are built thinking of groups. Groups can be as big as the leader tolerates, or as small as two. There is no size-based limits on who you can group with.

Players can define their own channels and there is both a newbie channel and some people ('Isatars') who are dedicated to helping newbies.

If you're looking for a very complex world where knowing the MUD and knowing other players are equally important, and where exploration never ends: hop in!
