Regarding the fifth installment, I'll just say that I tried playing it, tried watching others play, but it didn't captivate me; it's just not my thing. At the very least, what they did with the djinns completely finished me off... I wonder, under what influence was such a thing even created and approved...
Regarding the button, I apologize; I successfully forgot about it.
I've already written about the screens. Only a fool would definitively claim that this is good, and that is bad. Everyone likes different things. In the end, if you don't like the sixth installment, nothing will stop you from continuing to play the fifth. And the sixth game will still find its own players.
