The Wiimote (pointer) is very precise, what are you talking about? The ease of precision of aiming comes through in the simple Wii Play demo (shooting).
If the Wiimote relies on a centered crosshair, however, it does not show it's potential. That's why free-moving crosshairs, dead zones, turning speeds and cursor sensitivity were established in many games (while even the idea of a moving crosshair has almost died out on other platforms).
Your statement is just factually wrong.
I have already mentioned RE4. Its controls are about as precise as with a mouse but with a different gameplay/controls element (moving crosshair).
The Wiimote has revolutionized the soccer genre with PES 2008-2013 on Wii, but it was barely noticed (for the reasons I already mentioned). I was a big fan of the series prior to the Wii versions but I abandoned all soccer games since then because they are just boring without a pointer.
Every gameplay style except traditional fighting games works either as well or better with the Wiimote (compared to a gamepad which is the dominant style).
If the wiimote was so precise then we never would have got the motion plus addon. The PS3 equivalent of waggle controls is better still. Go for some of the modern VR stuff or more classical laser based affairs and it is not even close, go for some of the 10K+ pieces of electronics and then we might be able to talk. The claim it is about as precise as a mouse is laughable from where I sit. If nothing else we see people take great pains to have their gamepads work on PC games but the only wiimote stuff people are using for PC games is the nunchuck to stand in for a keyboard.
Or if you prefer then the classic point at the randomly generated target test -- for a properly calibrated setup in a suitably lit room then the coarse movement will be fine but you then get some kind of zeroing thing to make it precise, which is somewhat like a real weapon I suppose, but also means you are never going to be able to get as many targets as one of the other styles. Failing that watch someone enter their name or something on a keyboard overlay and what they do there.
Or for the more real examples. Friend of mine and myself went to an arcade (they still exist here) and had a great time with house of the dead there, silent scope and another such game. Couple of weeks later House of the Dead wii drops... so there we are with a nice TV, dark room, space to move and co-op against zombies in a game with a nice grindhouse aesthetic. I have had worse quasi light gun affairs, mainly as he and I had suffered through some of the PAL "for whatever reason we imagine there are no lightguns in Europe, better give them dpad crosshairs instead, also censorship aplenty" games back on the PS1, and while we eventually got through it then it was more of a "so we can say we tried" affair both of us would have jumped at the chance to instead do a PS1 effort back on his old 17 inch CRT back when, never mind with the kind of setups we otherwise had then.
Like what you like but to call the wiimote some kind of unfairly dismissed effort in controls is utterly laughable. While I imagine some kind of glove/squeeze box will be where things head (assuming we don't get neural interfaces first), or maybe a super precise camera, I could see the ideas that underpin the wiimote coming in at some point but the wiimote itself was way too early for the tech to be viable as an out and out competitor. You can design around it (I would probably have Resident Evil 4 Wii as an example of that, with the base game also lending itself reasonably well to it too) to some extent but other than name entry and some aspects of minigames I can't get to the wiimote being.
I might have to look at this PES lark -- every type of football bores me asleep within minutes, computer game versions probably quicker than that, but if the controls are really that special then I should at least know. That said a token search has little and less in the way of evangelism for the Wii PES franchise (not to mention several people asking about classic controls) beyond it maybe being a bit better than the utter mediocrity of the PS360 efforts (For others playing along at home then PS1-PS2 era saw PES vs Fifa be one of the great schoolground divides akin to any other game series rivalry, PES was allowed to slip while fifa locked down a few more skins from real players and became the dominant method, before imploding into mediocrity and lootboxes). I would have expected to see something there -- you can find any number of articles noting the valve stuff I was on about before, and for the various other efforts at some level, even found a few people plumping for wiimote editions of the metroid prime games.
