Personally, I have learned that video games are a big waste of time unless you play it with your friends (brawl). Seriously, in RPGs, you level up to a really high level and waste a whole bunch of time on it. It really doesn't help you in any way except a way to pass the time. If your playing with friends face to face, there's also communication and bonding involved. Don't stay inside wasting your life on a video game.
Go play a sport, Learn an instrument, mod a nerf gun. These things are much more worthy of your time.
You can learn a lot more by not playing video games.
