Using a controller to play typical mouse-driven games sounds like trying to run the marathon without legs. Why cripple yourself?
Lack of a choice.
Too much mouse use, due to the arm position and movements required (and for whatever reason, the clicking) causes my arm to flare up. If you were to get up, bash your elbow into a wall 50 times, and then attempt to tackle the wall a few times with that shoulder, yeah, it feels kinda like that. And it lasts for awhile. It's actually a back/neck issue, but it manifests in various semi-random ways. I go to physical therapy for this, which helps.... it's WAY better than it was one year ago. But for now, I can still not do too much in the way of gaming with the mouse. I can do some slow-moving games.... but not many. I have various pain meds for this, but they wont stop it from flaring up.
This has also had the side-effect of getting me really used to using the controller for everything. Minecraft is the main one that gets played the most, and I use the controller for literally everything (including stuff like inventory and menu, AKA, moving the mouse with the analogs). The one, and only, game that I cannot use the controller for is Starcraft 2, so that's the only one that cant be played. Even Diablo 3 is played like this (and I'm not going to try to describe just what I had to do to make THAT work). In most cases I'm actually better off this way, as I've always been astonishingly terrible with computer mice. Very, very inaccurate. I make up for this with extreme accuracy with a controller though (or pure keyboard, for some games). When I HAVE tried to play something like Minecraft with the usual keyboard/mouse, all that happens is I misclick alot of things, fall offa stuff all the time, and cant hit a damn thing with that stupid bow.
As for THIS game.... I honestly cant imagine playing it with the keyboard/mouse. I just immediately associate platformers with controllers as it is, and mouse aim would.... well, let's just say I wouldnt hit targets very often, hah.
