Anarchy Online is the only mmo that I have played that makes it possible to solo till darn near the end (depending on your gear, class and stat set up). I go on and on about that game, but it really is the best solo mmo out there.
Sure the graphics are dated, but it has more depth and content then any other mmo out right now. The best part is that half of it is free and the amount of free content will keep you busy for a very long time. Max is level 220 for paying peeps but 200 for non paying.
Pvp is there if you want it, but you'll need to be very good at twinking since they have evolved it to an art form.
It may not look very noob freindly at first since there are so many things to get your head around, but once you understand the basics, you will see that the customization is incredible.
Just make sure you go omnitek and not clan. Clan lands are ugly, dirty, and have trash lying around. They are basically the trailer trash of the future. ;P
The community is pretty good about helping new guys and as long as you ask nicely in general chat they will help you with any questions or give you advice on anything in the game.
If your interested, in trying it, The only difference in the servers is that things on RK1 cost a lot more then RK2 since it has been around for longer. The german server is also an option . The game is still in english but german speakers play on it and the people who answer your gm calls will speak german. It is the least populated of all the servers.
