It's about baseball first and foremost I agree.
And I for one am definitely going to be picking up RBI 15 on PC (Steam). I have it on PS4 and it's fun for a quick game of baseball, but I think PC modders can take it to the next level. It's not a simulation of course and will never be as good as MVP/2K with mods, but we have to remember it is not trying to compete woth those games. It's great for a quick 20 min game of arcade baseball, and it at least has stat tracking in season mode.
