They haven't done much to improve the crowd in the last 5 (or 10) years. I want the crowd to be just like real life. Screaming and going into a frenzy during clutch moments, making the hitter nervous (maybe shaking the camera a little). Reacting off the crack of the bat. Not waiting for a ball that is clearly going foul to land before they stop acting like it's a home run. Individual people heckling hitters (nothing obscene). Booing and leaving the stadium early when the home team is getting smoked. Maybe the occasional fan getting tackled by security for running on the field. Just little details that make for a cooler experience, instead of the same exact thing year after year since 2014.
They literally just put out the same game every single year, and I keep buying it because I love baseball and want updated rosters. But there needs to be some competition to force Sony to make a better game. You can play mlb the show 14 and there really isn't a big difference all the way up to 22. Some of the game modes are pretty cool, but gameplay wise they just collect your $60 and re release the same game every year.
I agree that it could be worse. But it could also be better. The goal should be to make the best game possible. They're always going to get the die hard baseball fan's money, but they could convince the casual fan to buy if the product is top notch. Probably won't ever happen, but a man can dream.
