I've been playing Hotline Miami and Papers Please on and off. These are amazing if you need a time filler. If you have a thousand hours to spend on a video game, nothing beats Dota2. It is clearly the best game ever made, but it takes an absurd amount of game knowledge to play properly. 108 heroes with ~5 unique abilities each and 128 items and the more you learn about it the more you realize you know nothing. NOTHING! also: you will be sodomized.
