@Hakase it's the same thing. read one of the article or watch the video
here's a personal example, when I had 7-8 games installed I'd always think for a couple of minutes "which one do I feel like playing the most" and then end up not playing anything at all
once I switched over to having 1 multiplayer game and 1 single player game things have gone much better, now if I feel like gaming I just launch the 1 game I have (be it single or multiplayer), play till I get bored and I'm done.
this way I also get to have a more "objective" view of the games I play, if there's a big annoyance or the game has some serious flaws, I'm more likely to notice it since it's the only game I'll play for a week or two, same thing goes for the positive things which really makes good games a long lasting pleasant experience
there are many ways to solve this problem and this solution is only one of many
