Anyone who thinks that touch screen buttons (with any kind of magical vibrator feedback, or without) is good/working way to play is just so wrong and have no idea of it.
examples of benefits of physical buttons:
- playing a game requires physical "borders" of buttons, aka your fingers know where the buttons are either by resting your fingers on the buttons or
- muscle memory(good idea where the buttons are without thinking) AND when player moves his fingers he knows when his fingers are on the right spot by his skin touching button edges.
-don't remember where buttons are? just move fingers along the controller and you find them, with on screen buttons only way is to look the display. (if you would slide your finger around in touch screen to find buttons = you would activate them by accident while physical buttons wont activate)
- Ability to click button with various speeds/forces. do I click it all the way down or just click it fast&lightly. remember ps2 analog buttons, 256 different states of force etc.
- depth of click/physical movement when pressing the button, it is impossible to mimic this with any kind of magical vibrator feedback.
playing mobile games that have buttons is just purely garbage. It is not "real" gaming, some games like angry birds work, but not more complex games.
It makes me mad to read this thread while so many just talk about things that they have no idea because they have heard about some haptic feedback and now are gurus of virtual buttons and think that it makes them comparable with normal buttons.
Easy to test:
1 Play some mario clone with phone and stream image to tv and try to play it without watching your phone.
2 Then play real mario with any console, even 8-bit nintendo.
Choose one that feels, works and is better method. No haptic thing can make touch controls be even in the same ball park as old school buttons.
I have maybe 10 different consoles, from nes to ps4+wii u being newest.
This control+display thing in wii u is 90% useless(few game types use it well and then it is good, like rabbids land is fun to play with it), if NX uses display in controller, maybe it is indeed for playing portable games, but even then buying extra controllers would cost too much (if) they all are portable console too.
I bet that IF nx uses display in controller, it is something similar that dreamcast had in mind, continue your game without the console or do some micro management etc.
