It's frustrating to be a newbie. Conquering the learning curve, finding your way around and fitting into the established world around you can be difficult and daunting. This can often be enough to stop new players from even trying. Of those that do try, many will give up and lose interest. Do not lose hope, though, there exist people willing to help you!
In Achaea, my favourite MUD from Iron Realms Entertainment, your character goes through a process called rebirth that offers a tutorial. Other MUDs have similar mechanics. Whatever the case, they will generally offer to place your character within a faction after a short time. Whether it's a guild, a house, a city or an entire country, the other members will almost always be happy to help you in any way they can.
Factions offer advice for newbies on how to get started, where to shop for essential goods and, most importantly, a purpose. You'll have a set of goals to complete to advance in rank and a larger, overall set to achieve as a whole.
If you're getting the help you need and but not quite the social interaction you desire, stick with it. Work hard in your faction; show that you're serious about becoming one of them. In time, they'll see this and accept you into the fold.
You'll also find advice on roleplay and etiquette for your particular game within your chosen faction. There's a lot to learn when you're new and learning these things, in particular, can be the difference between fitting in and being labelled a fun-killing lolplayer.
In short, if you have the opportunity to join a faction, you really should. New players have much to gain and little to lose. Besides, there's plenty of time for the lone wanderer routine later. This has been a short one compared to my previous entries, but it's important to me. I constantly see rogue newbies struggling with things that could easily be taught to them by a faction.
A place to make friends, learn about your chosen class and grow your character, that's a faction. If you have no clue what I'm on about, why not try something new? Iron Realms Entertainment offers a variety of top MUDs.
