OMFG Morrowind is great.
It\'s SLIGHTLY like GTA3 in terms of gameplay, but is pretty much a single-player classic RPG set in exotic(beatiful) landscapes. Time is unknown, nor does it matter.
Pretty much you start off, create your character, race, class(you can create), minor details of your figure, plus and minuses, skills, name, etc. Beyond that, you "join" clubs, and these councils, clubs, guilds, etc. will give you missions to perform. Upon doing these you will move up in the rankings, and people will like you more. Many factors influence gameplay, many of them under your control.
Along the way you will encounter monsters, sadly to say though, it isn\'t much of a battle system, especially if a hand-to-hand warrior. I\'m an Archer/Dagger thrower, so it can be fun trying to kill from a distance.
This is truly a must have for any RPG fan though, I consider it to be the ultimate RPG.
