How Many Buttons Are Too Many on Display screen?

I've mentioned this time and time once more, however I’m actually not a fan of contact display screen controls. I really feel like they restrict Devs on their design choices, and I really feel like they're cumbersome for gamers. I've seen the clamoring from individuals for extra controller assist, which is simply music to my ears.

I actually want it had been viable to only not have contact display screen assist lol, however I do know that's not real looking. No my query is what number of buttons are too many for you on display screen? Video games like Alien Isolation have inputs on display screen and a few video games have a cramped 12. Madness

What do y'all assume? Personally, when you recover from like 8? it type of will get to be loads.
