To be honest, technology isn’t the main factor to be amazed with but the fact that we are going to get such AAA games even when iOS nor Android are the market for it, you know, they are no Candy Crush or any regular gatcha game…
I don’t even have an iPhone anymore, but even if I did I wouldn’t get those titles there, I will never forget Apple (or Epic or whoever fault is) to turn their back to Infinity Blade games, the third one even was a tech demo with an iPhone presentation FFS! (Does that ring a bell BTW?), and so many other good AAA like games have been lost in the time, especially with iOS.
