Well, obviously it wouldn't work for all genres. I'm talking more specifically about first person shooters. It's just that PC gamers always tout the superiority of the keyboard/mouse combo, but to me, it's like they are really talking about the superiority of the mouse look over a right thumbstick. I agree that mouse look is going to be many times more accurate than a right thumbstick. PC games don't need aim assist like console games do, because the mouse is so much more accurate, and I have no disagreements with this.
But in terms of character movement, there has to be something better than using WASD. You said that you're not going to drop the nunchuk and then kit a key, and then pick up the nunchuk again, etc, etc. I understand your point, but couldn't a left thumbstick simply be built onto keyboards themselves, and basically become a standard?
Or maybe keyboards could have a latch on the left side, where you attatch the nunchuk control to the side of the keyboard, and just snap it in place. You use the mouse as your right thumbstick and the nunchuk thing as your left thumbstick. It might seem kinda awkward at first, but I'm guessing that once people got used to it, they would wonder how the heck they dealt with WASD for all those years.
The superiority of keyboard over nunchuk comes from this simple math: how many buttons you got on nunchuck? depending on number of axis it supports 4-16, maybe extra 2 on the sides. keyboard? 100. obviously you not using all 100 while gaming with wasd setup, but advantage of keyboard is not just wasd, but the proximity of extra 20-30 buttons to the said wasd. Those "extra" buttons are essential for quick and effective gameplay.
Even in an FPS that you claim you only need nunchuk for. How are you going to crouch, jump, switch weapons, reload, open doors, switch from run-walk with just a thumbstick in your hand?
yes, there are mouses with 10 buttons, so you can move those functions to the mouse, but then who are you really helping? moving button responsibility from one hand to another. mouse hand is already got enough work to do.
So to sum your topic up, the primarily reasons keyboard + mouse is considered superior to console joypads:
1. mouse is more precise than right thumbstick
2. keyboard got more buttons than joypad as a whole, even if it lacks analog response
And to answer the MMO gamer, if you only using your keyboard for WASD and rest of your functions are moved to mouse, that is a very inefficient and slow gameplay style and there's absolutely no need to purchase a thumb stick just to replace 4 buttons on a keyboard you already own.
I'll give you an example of my experience with MMO, I used to play Ragnarok Online. If you're not familiar, mouse was used to interact with the targeting + movement. Keyboard was set up the following way: rows Q-], A-' and Z-/ were used as hotkeys for spells, equipment and items usage. Plus if you needed to open inventory, status window, etc there were keyboard shortcuts for that, instead of clicking HUD with a mouse.
So just because your MMO experience hasn't been very requiring of the keyboard function, do not belittle the advantage of having one.
