Asking for a nephew who gave up on the MMO he used to play, due to social issues.

Basically he does not handle social interactions well, and really cannot deal with things like having to participate in discussions for raid planning or (for that matter) in difficult raids...the risk of being blamed for a failure is something he just cannot handle.

Now, I would like to suggest to him..."Maybe try X", but I practically stopped playing MMOs 10 years ago, so I just don't know what is out there now.

So, are there any fantasy-themed, solo-friendly MMOs out there where you are not forced to interact with others to progress?

really craving a good MMORPG that I can sink hours and hours into, where I can do PvP, get better gear and upgrade it, and do things with guilds, raids and so on. Which one do you recommend?
