Up until a few months back, I thought I was like you: spent most of my time in front of a screen for work, had played a few games, but didn't feel like a gamer anymore.
Then, my best friend told me Witcher 3 was amazing. I had bought it, but never played it, because of the reasons above. So, I gave it a try.
And man was I wrong...
The first weekend, without the wife and kid home, I played 8 hours a day. And I'm happy to progress after work. Not every day, but several times a week.
Maybe you're like me: you need to find a game you like. And you'll be a gamer again.
