Actually, the answer for small screens is specially for porn games. A lot of people cannot comfortably enjoy them on a laptop or desktop IBM PC, so they need a device they can take with them into their bed so they can comfortably play these.
Unfortunately, the developers did not listen, so people like me risk hurting their neck and back to play these in bed by using a laptop.
Not to mention, my Pixel 7 Pro has a much better display than my laptop.
I thought smartphones based on the arm64-v8a (or in some cases, armeabi-v7a) were actually the largest market for computers right now, and yet, despite having a larger market, they have a far crappier gaming experience.
The very robust selection and extreme amount of fine-tuning of emulators on that really old business laptop vs… all Android gets. The only Sega hardware that is emulated on Android is the Dreamcast. For Saturn and below, there is nothing. Even weak IBM PCs just have a very robust library of games that smartphones have stopped making attempts to catch up to.
Technically Dreamcast emulation is superior on Android over anything else… but you can easily run Android apps on an IBM PC.
