One of the few things that bothered me about the game since I came into it via PS Plus this year was the fact that the classic stadiums were all way too expensive. They used to be around 1,000 stubs when I last played in MLBTS 22. Now they're 10 times that. The classic stadiums are a vital part of the game, IMO. Maybe the stadiums should all be free.
I was glad, though, that the number of unlockables in the market was way down. It was crazy to have them all there.
One other thing: Make the bonuses for collecting uniforms more than 20 packs. Maybe add some 99s.
