Fear teh 1337 Elder Scrolls fan(aka, me

).
The complete name of the game is
The Elder Scrolls IV: Oblivion. It is the latest in a long line of CRPGs.
First, a bit of history on the series...
The Elder Scrolls: ArenaThe series began in 1994, with Arena. It was made freely available by Bethesda Softworks on the Elder Scrolls 10th Anniversary(get it
here). The basic gameplay of Arena is similar to that of Oblivion(all Elder Scrolls games, in the main line, are similar in basic gameplay). Arena likely had, at the time, the largest "game world" ever created.
The Elder Scrolls II: DaggerfallIt likely STILL has the largest game world ever created(despite being released in 1996)... ignoring games with an infinite gameworld. It is also one of the buggiest games I have ever played(even AFTER it was patched

)... some people called it Buggerfall, I believe. I have played little of Oblivion(I don't own the game, I played it elsewhere), but for the time being, Daggerfall is my favourite in the series(discounting mods).
The Elder Scrolls III: MorrowindOne of the Xbox's big-name games(released around the same time as the Xbox, similar to how Oblivion was released shortly after the Xbox360). Morrowind lacked the huge gameworlds the previous two had to offer, but made up for it by handcrafting most of its gameworld(no more generic people/towns). It also came with a Construction Set to make mods with(mods were created for Daggerfall without one, but they were nothing compared to what people have made for Morrowind). Two expansion packs were also released.
The Elder Scrolls IV: OblivionThis one takes place in the Imperial region(unlike Morrowind, which took place on a string of islands). The technology has advanced a great deal since the last game, so no need to go into that. And it returned ridable horses to the series(previously, they were only ridable in Daggerfall).
Overview(what they all have in common, and the basic gameplay)
They are played from a 1st-person view(Morrowind and Oblivion allow you to choose a 3rd-person view), have fairly strong storylines, are open-ended(it lets you do what you want, there is no goal... thus, it is very difficult to say you finished it), allow a great deal of customization of your characters, have enough clothes/armour to make them seem like a fashion-sim(

), have large gameworlds(though the last two are tiny in comparison to the first two), and have political systems(you are not getting in the good graces of all of the groups), and LOTS of books to read(we are talking professional-quality "books"

).
I'll leave out the Elder Scrolls games outside the main line(such as Battlespyre, the Elder Scrolls equivalent of MoE).
