Oh @KindaKreator - I am not saying they’re written in some book, just that your sales will simply be better for certain types of games elsewhere. Nothing prevents you from making a PC game that requires a controller, but I guarantee you’ll lose sales compared to whatever that game is for console, simply because not all PC gamer players have controllers (in fact, a huge chunk still don’t). Strategy games just historically underperform other genres on console, while still being a strong genre on PC. Has to do with the markets of these. It was just two examples of many general rules of thumb as to what games are best where (nothing prevents you from making games that don’t fit this trend). IE: Did you know that a WW2 strategy game set in the Eastern Front will outsell a PC game set in the Western Front (or N. Africa) by a huge factor, all other things being equal? Just an example of biases customers have 
It doesn’t mean you can’t make a successful West front game, it just means on average you’re better off starting in the East.
(I used to be the marketing guy for one of the large war strategy game publishers… so my example is speaking to that experience)
Anyway, that’s an aside to the overall topic!
