Still in its beta, MU Online has a lot to offer. I suggest you check it out. It is currently the number 1 game download from
www.download.com with about 86 thousand downloads. Its a top down perspective mmorpg. Click to walk, etc etc. 3 classes, elf, knight, mage. I give it a 4/5 only because i dont like the top down perspective and there is a small learning curve. Here are the links.
