Yeah, that does bring up the question: Why not just get the PC versions and run them on the machine you're already using?
And yes, PC games like those support controllers, if you want to use those. You just need the right drivers and such (which I can actually give you info about, if needed). Xbox controllers are the easiest to use, since it's Microsoft and all. I personally use a PS4 controller, it was pretty darn easy to set up.
Though obviously any first-person game is best done with a mouse/keyboard. But some players just dont like that.
And PC versions of both games support mods. As was said just above me, the games are VASTLY improved with those. Bethesda by itself is... a pretty bad developer, honestly. How they even managed to get to where they are is utterly beyond my comprehension. Since they're a bunch of useless twits, they generally just let the modders fix damn near all of the problems in the game, from technical issues to balance & content stuff. Consoles though cant do any of that.
