From what i saw of that video, its got elements that might be helpful, like understanding the failstacks system, but wouldnt say its a beginners guide etc. Its stuff thats useful to know before you get too deep and make mistakes. The sort of stuff you'd be doing in the first week most of it is pretty much reverseable.
Ive been playing for almost 3wks, and i think the biggest thing if found is to play it how its designed to be played, and not ignore what they want us to be doing. Its stupid, but i basically treated it like a survival game, stockpile everything you find, unlock access to new crafting options, and build my own little empire. However the game wants us to kinda cooperate and be focused. If you jump in deciding you want to be good at fishing, make tools, do lots of trading, and go round killing everything, well you can do that but its painfully slow because you dont have the infrastructure to, you need facilities (storage, worker lodging, workshops etc), and that requires CP (Contribution pts) which you'll gather by doing side-missions for random folks you meet.
If you follow the main quests you're given by the black spirit fella, and when you're asked to go to an NPC to do something then maybe take a look at some of the side quests and see if they seem doable. The game sends you to a few people along the way who'll introduce you to specific life skills like cooking, fishing etc and theres no harm in building a small enterprise of a couple of workers who go fetch certain things you can sell or use in the future. However pretty much everything has a min & max price determined by the game, which keeps the market in check, if you need something for crafting then most things can be bought from what others are trying to sell, so as ive found out lately, anything you're not planning on using or seems like its rare or expensive, its probably easier to just offer it up for sale rather than try and stockpile 80% of the stuff you loot, like i was
Find a crystal - oh maybe thats one i'd want later, i wont sell it cos it'll be annoying if i have to buy one later on, i'll just stick it in storage... with the other 30-plus, and look into it later :/
I ended up holding myself back because i needed so much storage to hold all the stuff i *might* need.
Im still trying to be self-sufficient with things, but ive accepted the marketplace is cheaper than vendors and with more choice, but quite often the impact of trying to do everything yourself is that it can prevent you doing other things. I rented a farm plot (4CP, which isnt that cheap) just because a quest wanted pepper in the ingredients. Took me a few days too, and all i needed to do was buy the damn stuff off the market and cook. It could have been a 10min quest - i got in my own way... and i still have that plot and havent completed the mission
You need iron - buy it, its cheap. Cheaper than buying access to an iron mine, buying the connections from that location to your towns storage, and then waiting for it to be gathered by your worker just because a mission asks you to build an axe. However mining because you want to sell the goods or know you'll need it later, thats fine. Its obvious, but worth saying.
The combat, storyline stuff, is pretty straight forward. The complexity is in becoming skill in certain professions.
On a side note, i mentioned i'd started a Ranger character, the first 15-20 levels i really wasnt sure about it. However around lv25 through random button mashing (and them being auto-unlocked as i hit the relevant lvl) it got so much better. Its got me wondering about some of the previous characters i'd started with, i was probably comparing the Sorceress at say lv35-40 with what i was starting fresh with, not realising that many of their skills are locked and thats why its underwhelming, im comparing a limited character with a fairly capable one, and thinking more AP isnt going to make them better because the mobs will get tougher too.
Screwed up a little yesterday too. Turned all my iron ore to shards, then turned that into ingots. I need steel, which is iron shards & coal, i'll keep some, but ive bought 2 more iron nodes & extra lodging to play catch-up. I did get a professional human worker though, so pleased with that.
