That happened to me from around 2003 to 2008. Games became too repetitive and uninteresting. I got back into them for a while but it wasn't until Dark Souls that I truly rekindled (sorry for the pun) my love of what games could be.
That was a game that perfectly recaptured my imagination and made it feel like I was a kid in the 1980s playing the original Legend of Zelda again. It was everything the modern Zelda games, which have always been my favorite series, had forgot about. I think Zelda regained its footing with Breath of the Wild which I thought was fantastic, but Dark Souls taught me that there is still great games out there if you look around. I started getting more and more into smaller, independently developed games and although I might not have as much free time, I love to discover new games that aren't just bog-standard shooters or annoying multiplayer games or AAA produced dribble.
