Elder Scrolls 5 : skyrim maybe ?
I already said that I'm against the Elder Scrolls games. As much as the characters appear to be customisable, the games all push you towards the same character. A vast majority of your skills (like stealth) are not actually useful beyond one or two optional quests. They are enjoyable as a 'pick up and play' type game like Grand Theft Auto, but are not enjoyable as an RPG experience.
Well, when it comes to the Elder Scrolls, you have to pick how you plan to play the character from the start, then play through. Stealth is a very deadly method of play that is exceptional at killing.
If you find yourself always doing the same skills, the game has no reply value. Try a stealth assassin with bow and alchemy, try stealth assassin with swords and illusion (they compliment each other very well). Try a destruction mage with armor, try another mage using conjuration or alteration without armor. Go sword and shield with without blacksmith and enchanting, using only alchemy.
Pick a role, and stick with it, then they become a lot more fun.

That said, it seems clear you like the Baldur's gate style of RPG the most. A party based, strong story game. Besides Dragon Age Origins and Neverwinter nights, and Mass Effect, I can't think of any others off hand.
