So what is it you want, exactly?
Every PC game sold still supports mouse and keyboard.
Do you want a game that only has, what, four or five actual actionable non-movement events? So that you only use WASD or arrow keys and everything else is literally done by a few mouse buttons?
Or, do you accept using many keys on the keyboard for actions such as toggling different items or switching weapons or interacting with the environment?
Many games may support controllers, but every single game on released on the PC supports mouse and keyboard.
Some may be bad ports that don't translate well to KB&M, but the support exists. Likewise, quite a few PC games support controllers, though said experience may be less than optimal.
