1. Fallout New Vegas
Hands down one of the games that I enjoy the most. This game is heavily focused on RP (Roleplaying) instead of the G (Game). The world is beautiful with many different interactions, there are multiple ways of getting something, good stories (The main plot is kinda meh though). There are somethings that were rushed what is a shame but you know, nothing is perfect.
2. Dark Souls
Now this is the opposite, they put more emphasis on the G than RP. The plot is beautiful but a freaking mass of you don't spend hours studying it. The combat system is great, it will reward you for actually learning, analyzing, and executing. It's a great game that you should give a shot.
