There are three times in your sentence that the word 'it' is used, and the first two undeniably refer to the game engine. If the third is meant to refer to the game itself you would be well served to use a different word than one you have already used twice in the same sentence to reference a different thing (a game engine).
Now, if you thought that the BB's were talking about the game as a whole in their front page blurb "play the most advanced basketball simulation and coaching AI..." I can understand your error. A simulation in the context of that sentence is a computer program that is used to simulate an abstract model of some system, in this case a hoop game. The other parts of the management game are not part of this simulation, and in some instances are not very advanced at all. That's not what the designers are speaking about on the front page, though. They are talking about the GE in the sentence in question.
Like I said, check out my team and my main rival. He has a ton more money than I do and has consistently done better on the TL. The only reason I have hung with him is because I have a lot more hoops knowledge than he does, especially early on. Maybe your hoops knowledge isn't as deep as you think it is.
I feel like I am managing a little make-believe basketball team. I have to worry about my arena, my staff, my roster, my salaries, my tactical decisions, injuries, several different competitions, and my scouting/draft. That to me is what a sports management game is all about. That's what this game is advertised as being, and that's what it delivers, in my opinion.
Once I scored a basket that still makes me laugh.
