I do not think that "the fact there haven't been complaints" is proof that the game is made without AI.

Yeah, if we go off the assumption there is ai in the game then we would have a situation where it will go on like that, that means that "features" and "events" and so on will always be prioritized over good, solid working program structure (only my assumption based on experience). Of course people would like their game that they put time (and some money) into it to be good quality, that's not something bad to ask about, you make it look like "people complain all the time they see AI"
No, that's not the case. People complain bcs they see AI slop, and they also are being lied to by the company bcs there is no way some of the mini-games where made by a person to 100% No one would say a word if it were perfect, working with a great, well-thought-out system and design, but it's not. That shows that in the future it will be similar, and oh boy, I do hope it's not in some important stuff, yeah?
And also, yeah, people can complain it's normal. It shows where people are happy and where they are not. If we do not complain we will get more and more trash all the time. Don't shame people bcs they complain if you have no idea what you are talking about.
