I decided I would make a brief return to video games for MGSV. I'm reminded why I quit them.
Video games build dependance. Their early levels are meant to lay a framework that idicates there will be great reward later on. As the game adds complexity, it adds more things for you to have to worry about. Whether it's wanting to come back and beat a level or to wanting to grind until you complete the game, these things are not actually worth the tradeoff in your time. Even realizing this, the time you've already invested keeps you coming back. That time invested does not go away. Eventually a game becomes a series, and a series becomes a genre, and a genre becomes every game that comes out. Then years of your life are gone.
Meta gaming can be enjoyable. Watching people take out an entire base with an anime cardboard box is hilarious. However, to get to the level of play and creativity to maintain gameplay like this consistently takes even greater time. This applies to building skill and familiarity in any particular game or games as a whole.
If you're still at a point in your life when games are new and exciting and you find joy in them, please continue your hobby to its completion. However, if you're feeling sluggish and find yourself wondering why you're still playing games, or you're thinking of going back, don't play games. Just leave them be.
