I updated the top post, removing Clok, since it seems to be down for good, and adding a few quotes from Dark about other Muds.
At some point, I will be adding Haelrahv to the list, because it's crafting is detailed and immersive, and there is an artisan class.
If you know of any Muds that are gone, or any new ones, please post here.

I would love to play Avalon, because it has the most in-depth farming and crafting I've found on a Mud. But I heard about the potential for a lot of OOC drama, and that put me off of it. Are things relatively calm there?

Hi Mirage, glad your back on the forum and maintaining this list.

I've tried avalon several times but always run in to the same problem, namely that the newbie experience is great, but as soon as I choose a profession, I just run out of stuff to do since there was no direction in the game that wasn't dictated by other players, and it seemed pretty difficult to start or find quests and solo activities, can't speak about drama, I do remember there was some sort of hoo-ha a while ago about one of the developers' abusive behaviour in rl, and about the game changing to be more cash grabby, but I'm not sure how that reflected on the game, as I said, I always had trouble getting into it, for all I loved the newbie experience.

On the other hand I do have some good news regarding some other games.

Wayfar1444, which was mentioned several times in this topic is now back up and running and even has a db page, and yes, it has the most insane crafting ever! You can literally build your own starship from scratch!

Coremud is also back up and running and the developers have  done a really nice job with the accessibility here, so that's definitely one to check out, indeed you can probably find the topic discussing accessibility changes on the forum.
one game I would recommend for this list is stellaraeon, it's not exactly got crafting or farming in the traditional sense, but it's got some very unique ideas, though what else would one expect for a game developed by Dentin of Alteraeon.

For a start, it's a space game with absolutely zero combat whatsoever, discover aliens, and talk to them, fly around the galaxy and do lots of mining minerals, stellar surveys, fulfilling cargo missions and the like. You don't build things in the traditional sense, but you can do things like refine your own fuel and ores, or customise your own ship components, idneed for exploration, especially considering the hole world is procedurally generated, there really isn't anything else quite like it.

Though the head developer is very busy  with her new job and can only work on the game at weekends, Erion has been expanding. There are now several new craftable items including candles, and prayer rugs, in preparation for a full faith and pilgrimage system which is coming in the future.

Another fun mechanic, which is none craft related, but imho is a fun one, is liberation. Forage for a feather of liberation, and use it to free captive prisoners or slaves you find around the game for rewards.

Okay, I'll confess I do have a vested interest in Erion since I'm writing for the game myself , adding story missions, background for different areas, and extra mobs to make things more interesting, indeed the feathers of liberation idea came from a suggestion I made which then got coded into the game.

@Jason
I don't know what happened to Clok, but I was sorry to see it go. A friend told me it was down for good, and when I checked it, there was no connection.

@Dark,
Would you write a bit more about each of those space games you mentioned? I'll copy and paste to the top post and give you credit for it. I find it difficult to get into space games, but I love Cosmic Rage, so that tends to take up my "space game" space, so to speak.
I love the liberation concept for Erion. That is amazing!

@Zack,
That's good to know. As long as there is no drama in game, I'll give Avalon another look.

ah... I guess it explains why people are over cogg now... maybe you could replace clok entry with cogg? basicly they are almost identical but diffrent, lol wierd thing to say but it is like that. for example, you could also farm on cogg, but instead of opening your own plot on the wildreness, now you have to pay for a land rent in shadgard and farm there. in adision to that, you could also tend to animals, like cows, chikkens and sheeps and use or sell their productions to the market.

@Mirage nice additions to the top post.

I will admit the feathers of liberation was actually my idea, since it kept bothering me that you'd see so many mistreated slaves or prisoners as background mobs in a lot of parts of the game, and not be able to actually do anything to help them. Aelyn liked the idea, and I'm really glad it made it into the game, indeed there will hopefully soon be some missions just connected with finding and liberating captives.

Both Wayfar1444 and coremud have db pages, so feel free to check for information.

Stellaraeon is rather different, and I'm not %100 sure whether it counts or not, since as far as I know you don't actually craft! anything. The hole game does revolve around mining and exploring though.

I notice you mention two towers, which is also a game I've been playing.

That's an interesting one since from what I can gather, the craft skills there aren't really a major part of the game and can't really affect your gameplay accept in roleplaying terms. However, I've run into a good few quests in the game that revolve around none combat actions, finding things, working things out, and yes, on occasion making things, often with great description and actions.

For example, one of my favourite quests in the grey havens revolves around helping the elf shipwrights build a boat, which requires a lot of different commands and detailed crafting actions, like steaming the planks to make them expand, bending them around the frame etc.

Another really nice quest involves helping a sick farmer in adornas in Rohan to plant his field, which includes hoeing the ground, digging and planting and watering the seeds.
There's even apparently a new quest for glass blowing too, so while the games' crafting activities are apparently fairly minimal, just playing the game in and of itself can often involve a lot more than just the usual hack n slash.

I thought 6dragons is down?

I'll take those Muds off the list.
Thanks to everyone for keeping me up to date.

I haven't played dark legacy, but I'd say it's a question of how much is there.
7th plane hadn't been under active development for quite a while last I checked, heck the newbie academy area was never finished, but there is still a lot to be done in the game anyway.

Funny you should mention Project Bob. I thought of that Mud when I was making the Dark legacy post, and what a loss they both are. I can't imagine putting so much time and effort into creating something wonderful, only to take it down. Same goes for Clok.

can you describe me how project bob was?

question: is there any significant crafting in Lostsouls, the game is so big and complex, I honestly can't tell with what I've played even though I've wracked up a dozen hours or so.
