This is just my opinion being a ~30 lifetime gamer, looking to see if I am alone.
I recently watched a movie length documentary on video games called just that, "Video Games". It was a fantastic watch and whilst it was obviously angled towards certain brands and games, it still captured a fairly accurate story of how we got to where we are now.
Gaming for me peaked around 5 - 10 years ago, new concepts, play styles, the introduction of internet gaming opening up the possibilities of what you could do from the comfort of your own home.
I played my first game of Battlefield Desert Combat, taken in by the openness of the battlefield and wide array of artillery & mastering the choppers whilst playing against real people rather than AI; this was just a taste of how good it could get.
I was then immersed into the World that was Warcraft, MMORPG's were the new craze. The game was never ending and ever expanding with the ability to grow within the game.
I could go on, however in the last 5 years I haven't felt like anything has really changed. Graphics are better, story lines are more engaging, gameplay is more in-depth, but everything seem recycled like I have done it before; it just now a little more polished.
For gaming manufacturers are simple taking a known brand, adding new content and re-releasing each title, rather than pushing the boundaries of new concepts and characters.
My assumption is the expectations from the public has become so high that the financial risks involved with exploring new titles could lead to their own downfall.
Considering more AAA games these days cost more to create than most movies, have we now created our own death spiral into simply rehashing marketable brands and not see anything new?
TL:DR – Cost to create games and expectation of the public has risen so high that creators are afraid to try anything new and innovative.
I was in a similar boat to you.
I gave up gaming (WoW) becuase it became too time consuming.
The only way I could keep up with the Jones was to cheat using bots. The bots would do all the farming so I could do pvp & raiding.
