I think this video showcases an interesting aspect of gaming that I never really thought about before. In their case, they play more games for a shorter amount of time vs spending a large portion of their time in few games.

Personally I'm on the side of spending more of my time in a select number of games. By far I have put no less then 3000-4000 hours in Minecraft. Logged by Steam, I got 1300+ hours in both GTA V and American Truck Simulator

More recently I've been really into Rocket League and Trackmania. These games are notable because I am constantly working to improve and get better at the game. As much replay-ability as much I find enjoyment in succeeding.

From time to time though, I do really enjoy getting into shorter, more story based games. Great examples being Portal 2, Road96, and Firewatch. What kind of gamer are you?
