Is it possible to build a robot to play games with?

This has been on my mind alot, but im pretty lonely and depressed to say, i have family members but they dont like what i enjoy like we cant relate to each other usually. I want to make a robot someday that you can play games with, like it can press keys on a keyboard and move a mouse, that type of stuff? The concept seems hard and pricey for someone like me.

Would something like this even be possible in real life? or is it just another dream?

Would it be cheating if im lonely? i feel like this could possibly help people such as myself or people who are disabled in some way.
