There are a LOT more games now, that's for sure. There's more trash, but frankly, a lot more good games too. Replaying some of the stuff I used to be hype for, I've been like 'wow this is ancient garbage'.
With the proliferation of useful engines/game development tools, it's become a lot easier to start making a game when you don't have to build the entire engine by yourself, but it also means an improvement in UI, being able to reuse ideas from past games, so on and so forth. Even stuff like proper galleries are a lot more common nowadays. Seriously, go back to some of the older early-mid 2000s games and replay them, many are hilariously clunky, have minimal/no save functionality, have no gallery and none planned... and that's not even touching on how many of them made it 0-1 updates after launch and got forgotten, same as today. If anything, I'd say that today a much higher proportion of games actually get regular updates.
So yes, I would absolutely agree there are more shitty games now than there used to be. Maybe even a higher proportion of shit, idk. I would disagree that is inherently a bad thing, it's just a natural side effect of lowering the barrier to entry.
Personally, I tend to loathe 3d renders and avoid most games with them unless they really look nice (House in the Rift for example), so that cuts me out of about 90% of what shows up on this site. But that doesn't mean 3d renders are bad, or that it' bad so many people use them. This is an almost unprecedented era of options, not all of them good, but at least there are options.
