Ahh another Dragon age fan I see! You should really play Dragon Age Origins too! The gameplay is a bit outdated because of the game's age but in terms of story and RPG elements it's by far the best Dragon Age game.
My list:
The Witcher Trilogy (Every game in the trilogy is awesome!)
The Elder Scrolls IV & V
The Mass Effect & Dragon Age games (Both series are by Bioware Studios so I decided to group them together, these games are by far my favorite games and play through the whole series atleast once or twice a year! Can't wait for the Mass Effect remaster )
I'm more of a fan of the earlier Assassin's Creed games but I do like the added RPG elements in the latest couple of games
Mount & Blade: Warband
Fallout: New Vegas
Sleeping Dogs (Technically not an RPG but contains a lot of RPG elements tho)
Sunless Sea
