Doesn't matter anyway. My reflexes aren't what they were when I was a teenager.
I feel like a more "proper" solution would be to come up with shooty-shooty bang-bang game mechanics where "ability to aim with finesse at the things you're shooting at" is mechanically irrelevant, so that "aiming at things" isn't really a part of the console or the PC experience. I.e., design the game so that, despite complete ignorance of your input method, there is still absolutely no advantage in using a mouse compared to a joystick.
Any ideas on how such a thing could be accomplished?
• Maybe a game could snap all the people to a 3D voxel grid. You'd move smoothly, but your "shadow" would always exist within a certain voxel; and you'd always see everyone else over the network as popping between voxels. To shoot someone, you just have to target the right voxel.
• Maybe a game could give people, instead of hitscan line guns, extruded hitscan beam weapons of some diameter. Everyone is blowing 1m-wide holes in one-another [and the terrain] with giant laser cannons. I'd play that!
The thing is, even if you remove the finesse, mouse may well STILL have an advantage. I can whip a mouse around to do a 180 far quicker than I can on a controller.
Well-made motion controls (to the point that motion controls from any other shooter feel terrible) really feel like mouse-level precision for Splatoon.
On the other hand, Splatoon is a third person shooter so it may not translate too well to a first person shooter, although you do get first person perspective when using a Charger, the game's terminology for a sniper weapon, with a scope. Not only that, but I remember the addition of motion controls to the Switch port of Doom being considered such a huge upgrade it might as well have been a new game.
I'm with you on auto-aim being a sad hack. Having been a rabid Splatoon player for the past four years, I tried Overwatch on PS4 and just gave up after a while — I don't want my performance tied to arthritic finger bending to try and convince the game to auto-aim for me, I just want to point and shoot as I've been able to do very accurately with the Wii U GamePad and any Switch controller, especially when the PS4 controller supports motion control.
