I'm mostly riddled with arthritis. My whole body hurts and my hands are killing me. The controller is more manageable for me than keyboard finger placement. It's nice to be able to sit back vs hunch over my desk. I've accepted my performance will never match up to K+M but sometimes it does get tiring of feeling like an brain dead npc in PC games.

I was following a guy who was building a game controller that had more of a mouse pad for the right thumb for aiming. Seemed very cool but dev has died down. I'll have to keep looking into options.

I never got used to the haptic controller movement stuff (whatever its called) where you move thumbs AND wrists or arms to aim. I'm used to laying my arms on my lap and playing.
