Funny thing with this thread is that it died for a month because all the conversation happened on discord. And now Discord is so active that we're talking about doing forums. So I guess I'll keep dumping newbie tips here.
Stuff that needs doing:
Idle friendly:
Farming/animal breeding. It's slow, you can log in once a day, plant and harvest. Probably consider getting some armor and combat skill to defend your farms. We used to have lots of food when we had about 5 active players, now a lot of stuff is getting foraged/fished/hunted out, so a steady food supply would be nice.
Crafting. Convert boulders to blocks. Make bonemeal, clay pots, glue, balm. There's a lot of grindy work out there, and it's a quiet way to grind up some skills while waiting to grow out of the adolescent stat penalties.
Cooking. It's a vital skill for everyone, so you might want to get it up to at least level 1 or 2.
Tailoring. Turn twigs to rope to thread to cloth. Pick up a good knife at the Hub. Later on you can do the same with linen thread and cloth. Linen is probably one of the more valuable resources right now.
Leatherworking & clothesmaking. Go to the Hub and there's plenty of deer hide lying around. Convert it all to leather. It's valuable and you can use it to convince someone to make good clothes for you. Tracker gear can last two lifetimes, help you through winter, and is one of the best armor we have.
Low level smithing. Meet up with a smith. Turn wire into nails, or metal parts into pick heads, spear heads, etc.
Not so idle:
Hunting and fishing. Everyone should get high enough level to hunt deer. Fishing is optional, but more useful if you're going to do exploring, especially in places where game is rarer or harder.
Foraging. Silver nettles last a while and are used for a lot. Razorgrain is needed for training dummies and housing. Fruits are the best type of food.
Smelting. Smelting mechanics can be a bit complex. You need to pay attention once every hour. But for the first level you can drag some limestone and coal outside of Hub (to lose the smelting bonus) and make some lime. Lime is needed for parchment, steel, and glue.
Smithing. Smithing in itself is low activity, but the materials are in short supply, so you'll probably have to do mining and smelting yourself. If you want something super high value in the long run, this is probably it.
Mining/spelunking. There's some ore on the surface, but the underground is where the good stuff is. Underground is dangerous; expect to take a lot of injuries as you grind spelunking early on.
Jewelmaking. The work itself is not bad, but parts like willow and gold are more difficult to find.
More active roles:
Dangerous animal hunting. Wolf and bear are core to our economy. You'll need to spend time hunting them down and possibly training too. If you're even more hardcore you can tame animals too.
Dungeon crawling. There's a lot of good stuff in the dungeon, like metal helmets and flour. We probably have the gear to go much deeper. But it can't be soloed, and nobody has gone too far.
Scouting. We've reverse engineered a lot of foreign tech. At the very least, it's good to know where the orc cities are, foreign resources, good places for new cities, unexplored dungeons.
