There is indeed an elder scrolls game that is a multiplayer game. It it called elderscrolls online. Pleae look here: http://elderscrollsonline.com/en/
As for the other Elder Scrolls games, you can get Morrowind or Oblivion for much less than $60.
The best thing, I've found, about the the Elder Scrolls games is this: You don't have to do to a lot of the quests at all. You can just wander around looking at the beautilfull scenery, picking flowers etc. As for the combat, yes there are combat in these games. However there is a difficulry slider you can turn all the way way down to easy mode (or very easy, maybe).
And as the others have said, combat is mostly clicking with your mouse. You're able to sneak also. My best advice would be this: play an archer type character, get a bow, and sneak up on people, either from a distance or with a dagger.
As for the controls, I think? you can play these games, Morrowind, Oblivion or Skyrim with an Xbox 360 controller. It is sometimes easier for people who have arthritis (sp?) to play games using a controller for xbox 360 (or for ps3).
