PC Game with good Story and unlocks/Collectables??

I am looking for a good PC game , RPG if its out there that has: Good Story, Lots of Unlockables, Lots of hidden things to find, Lots of side quests to complete. Maybe even something where you get graded on the side quests so there is a good reason to replay them. Like Just Cause 2 and Saints Row games, where there is a lot of things to collect, Unlocks and Exploration. Any ideas? Doesn't need to be a RPG.

Batman: Arkham Asylum / City

Borderlands 1 / 2

Deus Ex: Human Revolution

Dishonored

The Elder Scrolls V: Skyrim

Fallout 3 / New Vegas

The Incredible Adventures of Van Helsing

Magicka

Terraria

The Witcher 1 / 2

Deus Ex: Human Revolution.

kingdoms of amalur: reckoning

Planescape: Torment. Lots of side quests of incredibly good quality. Lots of hidden stuff to find. Every single piece of dialogue is excellent, and it not only has a good story, but it also has some of the best characters i have ever seen in a video game.

The User Interface is clunky, and it plays like an adventure game - Explore, talk to people, solve puzzles, etc., but it's worth playing because there is no modern equivalent that comes close to its quality. The graphics are beautiful in HD resolution aswell.

Not too many great 'story focused' (writing/characters/dialogs/setting..) RPGs. But yea, Planescape is the obvious choice.

You also have other good ones like...

Vampire: Bloodlines

Mask of the Betrayer

Arcanum

Fallout 1/2/NV

KotoR 2

Deus Ex

Betrayal at Krondor

NWN modules like Adam Miller's Dreamcatcher and Shadowlords, Elegia Eternum and Excrucio Eternum

Anachronox

Witcher games are decent

Game of Thrones RPG supposedly is strong in this area (if you like the show)

Not 'pure' rpgs but...

King of Dragon Pass

Quest for Glory series

Bloodnet

A bunch of adventure games have good story elements like..

Blade Runner

Tex Murphy games

Jane Jensen involved adventure games (Gabriel Knight series, Kings Quest 6..)

I have no Mouth and I must Scream

Gothic :D
