Mass Effect Legendary Edition. Play the game on story mode and enjoy it. That trilogy has the best characters and some of the best quest storylines in the industry in my opinion.
Mass Effect trilogy. It has amazing characters, get stories, and the gameplay gets better with each game. Though the first in the series is still my favorite, and one of my favorite games of all time, 2 is considered to be one of the best character driven RPGs in recent memory. Bonus, you can get all three remastered via the Legendary Edition.
