Like almost everything, suspension of belief is by degrees. Most films and games require it to some extent, and you don't mind that, necessarily.I enjoyed DS a lot more than I thought I would, I did 100% it in the initial Covid lockdown which was quite apt.
I thought it was quite innovative if sometimes frustrating.
But agree fully with it being Kojima indulging his artistic desires. I approached it like a particularly arty film where you need to suspend logic processing and just experience it.
That said, I rate games where that approach is not required much higher, I'll take MGS1 or 3 over his other games no question. I fear his ego will grow too big and the sequel or any other games he makes now will stray too close to pointlessly cryptic and annoying.
But at the other end of the spectrum nothing makes sense, and every chapter retcons the previous one. Because 'auteur'.
