Ah guilds, they are useful in some ways, but......to many people join them for the wrong reasons.
I have been invited to join 4 guilds, I turned them all down because I simply didn't know enough about them or them about me. One made me laugh, a character (a complete stranger) came up and said to me, "would you like to join our guild, it's a secret guild." Yeah right, big secret now friend, haha.
I have now developed my character to a point where it might be worth looking for a guild and asking to join, but up till now I have spent all my time as an individual and had no problem moving forward. Part of my early development was spent with other newcomers who joined around the time I joined, I knew they were newcomers because they were down in the sewers killing rats with me :-) We talked, discussed problems we had, compared notes on areas and quests, it was a good time. Many of those newcomers joined guilds, most are now gone, I am still here.
So do what what the game is about, RP, get a group of friends about the same level and travel in a group, explore the lands and watch out for danger, if lost find the nearest road and follow it, it's bound to lead somewhere.
If looking for a NPC character RP it to a more experienced player, yes it's true some of them won't respond, I ALWAYS do, even if it is to apologise for not being able to help them, you will soon build up a good idea of which players are happy to help and which playes aren't. Good luck.
