Regarding the first post: It seems to me to be an excellent mechanics guide, of which I don't think there would need to be more than one. That is to say, you're explaining how to learn to play the game and merely using a priest as an example (which is also a good as it's the easiest class to become involved in roleplay, since people will seek you rather than only the reverse).
My specific suggestions are listed below.
- Add URLs to each of the HELP instructions, so folks can read the help for any given command right from the guide.
- Remove level numbers (e.g. "1-20" and "6"). They're not visible in-game so you could end up confusing them.
- Spell check - just a minor thing given the size of the post, but it all adds to the quality of the guide
- Add in the good explanation later on in the thread of training skills/spells vs. training levels (since they both involve spending hard-earned experience points).
- Suggest being less concerned with exact level breaks than the concepts you're trying to explain (e.g. referring to the change from using a weapon to using magic for inflicting damage could be left up to the player as to when they do so, but it's a good concept to explain).
I think there will always be a knowledge gap from when a new player works out how to connect vs. when they actually feel comfortable moving around and advancing their character concept without having to read help text. The fact is, we already provide ALL the help they'll ever need: it's just that it happens to be a long list of individual help files that folks will never painfully trawl though beginning to end. So a quick-start guide is a useful bridge.
I do think there is a danger in providing anything that looks like a "walkthrough" though - I myself would probably feel rather jaded if my in-character efforts to learn the game from scratch are stomped on by twinks who have simply connected to the game for the first time and then followed a walkthrough immediately. The lack of IC information is what helps your case in this regard - naming pet NPCs though is probably not necessary; perhaps "Ask around about what pets are sold in your starting city." would be better.
Last piece of advice: there is always a danger in any guide to expand it ad nauseum until it's really a reference manual instead of a quick-start guide - feel free to cull sections if they aren't a core concept that newbies would need to get going.
