I personally am only playing 2021 and 20 as I still have a lot to do on them. My biggest complaint is that the mode feels like it's just a never ending string of single games. None of what you do has any meaning to a career mode. You don't interact with the fans, media, your teammates, fellow players around the league or your own agent.
Salaries mean nothing because you do not do anything with the money. You don't see a chance to see a lifestyle change once you make it big, nor do you see what happens if you turn out to be a bust. I never bother negotiating as the money is pointless. I simply am signing small 1-2 year contracts in case the team starts going south quickly.
This marks a return to playing since my RBI baseball days, and they didn't have online in those days, but the gameplay was far more fun. I won't say it was superior or inferior, but I just enjoyed the various modes more. I won't bother complaining about RTTS as I suspect they are going to phase that out and just have everyone's CAP in DD and be done with it. I don't know if that's good or bad, just what I think will happen going forward.
