I think you are perhaps getting a bit attached to that one particular word. Mr. Norris89 may or may not need to run old Windows games the way he probably needs to breathe, but he can certainly say “a computer needs to run old Windows games if I’m gonna buy it”. The phrase “I need to run old Windows games” is easily understood as that.
