I played a little baseball as a kid (as well as played in co-ed rec softball leagues as an adult). So I knew most of the rules of baseball prior to playing this console baseball game. But this MLB The Show game has still taught me many additional nuances of the game that are not easy to pickup unless you are a hardcore baseball person. I still have tons more to learn, but from that perspective this game has taken my knowledge of baseball to a level I did not have prior to playing this game.
Now this game is configurable, so yes it can be newbie friendly as long as it is configured for "newbies". But you don't want to be too newbie friendly. As an example when batting, you do not want every pitch to be in the strike zone. You do want the pitchers to throw balls out of the strike zone so that you get into the habit of learning a sight picture the split second the pitch leaves the pitchers hand to know if you are swinging or not. But when pitching is configured at the newbie levels, most if not all pitches will be in the strike zone.
Oh and prior to playing this game, I was not very good at identifying pitch types coming out of the pitchers hands. They all kind of looked the same. But in time as I have become a better batter, I am slowly getting better with most pitches. But there is still one pitch type I have not even remotely come close to mastering as a batter and that is the slider. When the sight picture is completely out of wack, I can recognize it and not swing. But a well thrown slider that paints a corner continues to plague me. Coming out of the pitchers hand it looks like a fast ball. But the moment I begin my swing as I would for most fast balls, the damn ball begins to break and I swing too damn early. Sometimes I get lucky, but most times I wif. Dang I hate a well thrown slider.
