Pick up The Orange Box (https://en.wikipedia.org/wiki/The_Orange_Box https://en.wikipedia.org/wiki/The_Orange_Box). It includes Half Life 2, (plus the two sequel episodes), and Portal. Portal is a fantastic game, with a surprising amount of story given the fact that it appears at first to be a fairly simple puzzle game. Half Life 2, is a great first person shooter, again with great story. What I like about these games is that they're immersive, without being overly long or tedious. You can play through Portal in a few evenings, without feeling like you're missing out on hundreds of side quests. The gameplay is tight, fun and innovative.
