They Are not that hadr to learn. The Buttons are really easy. The only hard part is to know where stuff is and where can you go for different quests but don't worry you wount be he only one for this game hasn't came out yet (As you probobly already know that). What can really help you is if you join a kinship. Your kinship member will really help you out a lot, with good weapons or good quests, or even to protect you.
Oh no there are many things you can do. You are always going to be one step behind the Fellowship and moral values will determine what class will you become. Like for elves there is an archer and avenger. Archer is if you are good and follow the advice of the Valar but avenger you are corrupt, still good, but evil. Like a Good Bad ass. Oh and what you do may effect the fellowship. But not like only you but what all of the players do.
