I'm a huge Dragon Age fan, and 2 is my absolute favorite. It gets a lot of (perfectly valid) criticism, but the 'found family' themes really resonated with me. And I love how it focuses on the people in this one city instead of having a big, save-the-entire-world narrative like most RPGs. It felt so personal.
Plus, snarky Hawke is one of the most fun protagonists I've ever played in a game.
