Just finished Saints Row IV myself. I do agree that it's pretty fun and the ridiculousness is what drew me to the previous one and this one as well, so it's a big plus in my book.
It's true though, as I grew up I too became more and more critical of "modern" video game design. There are still good games out there, however I do dislike how vastly homogenized it has all become. I prefer variety even within one genre (for example, it used to be shooter and cover-shooter, now it's (cover) shooter and the occasional action shooter, whatever that is) and I especially expect variety between different genres, but I'll end it there to avoid going into a rant.
