For context, I wasn’t very excited about Skyrim when it came out, but then had lots of fun playing it once I picked it up.
With Starfield it’s even “worse”, because I don’t even consider playing it at the moment. The game’s setting doesn’t really suit me that much.

I think the state of modern games has slowly changed over the years.

A lot of them have a set formula that we’ve all become accusomed to over the last decade. Especially with AAA games it’s all quite streamlined. Every major studio has some sort of game design style and there hasn’t been that much wiggling room.
I was able to enjoy a few newer games eventually, but only because the game universe interested me in the first place and I sort of forced myself to start playing.

There are also lots of indie games, but to some degree I feel like they also follow some kind of gameplay style patterns.

Very rarely do we get something new and super exciting. I believe the era of 2006-2016 was an outlier, where a lot of new ideas were technically viable for the first time due to excellent console and, at the later stage, PC performance, which skyrocketed a lot of innovative ideas. Both for AAA studios and indie developers.

That being said, we still get new exciting games every now and then, but they’re harder to find, harder to finance while retaining creative liberty, and it’s more difficult to convince players to start picking it up in a sea of games.

So I wouldn’t say that you’re getting old, but more like the gaming industry is getting old similar to the movie / tv show industry, where we’ve had this pattern of usual mediocreness for quite some time.
