I unironically think gaming is the best it's ever been, as far as the number of quality games we get, but obviously nothing is perfect, and If I got the power to change anything about it I'd probably, in no particular order.....
1. Stop developers from making every single game an open world game. Open World games are great, but so are linear games
2. Stop developers from trying to make their open world games "bigger" as a selling point, I think open world's were too big in the mid 360/PS3 days, let alone now. There's way too much bloat in games, but also just the fact that by making an open world hilariously large, it becomes less memorable (too many areas to memorize), more generic (oh look another empty hill with a couple trees on it), harder to navigate, and just makes people desperate to use fast travel so they don't need to spend 30 minutes simply getting to the desired location.
3. Unpopular one, but stop devs primarily focusing on graphics, gameplay has always been king, and things like AI and physics haven't had any meaningful advances in a long time, plus, while games could always look better, imo we're well past the point where it's diminishing returns. And I'd rather not wait 5+ years for every game because they need it to look marginally better. If graphics had stopped advancing in the late 360/PS3 early One/PS4 era, I wouldn't have minded at all if it means quicker game releases and more focuses on the other stuff besides graphics.
4. Stop the massive focus on microtransactions, I don't mind cosmetic microtransactions in theory, but when games started giving you basically no cosmetics and made it incredibly grindy to unlock anything even slightly cool, it was kind of annoying. And then things like buying characters or items in online multiplayer games, basically paying for advantages over other people, that's scummy. That also goes along with my 3rd point, if devs stopped focusing on spending so much money improving their graphics, and having games take super long to make, they might not need near as much microtransactions
