Why there must be at all a strategy guide?

Got the Sims bought 4 Limited Edition and the game guide to ... Honestly? I like the Sims4 not so good. Just me being able to make the interior design more flexible missing the opportunity. The clothing of the Sims do not like it. Too little imagination and frumpy. It is good that there is a game guide for people who may enter only at DieSims4, but honestly ... There are game developers, who have studied and have the Sims 4 developed over many years. Why does the game does not explain by itself? Why must still give a "game guide" for the user in such highly skilled people it? While there are many "screen shots" in the book, and some (explanatory) lines to but solutions? See solutions for me different. Too bad. The money I could have saved me. Very disappointing. Because I stay with the Sims3.
