Matt Birchler, in a member post, points out that Call of Duty has both massive computing requirements and a complex interface, and still “normal” folks figure it out just fine:

None of this is to say that good user interfaces don’t matter, of course they do. I do think it’s a good reminder of two things:

  1. The “average user” is more capable than we give them credit for
  2. People will tolerate a bad UI if they enjoy the product as a whole

A good reminder for all of us pontificating about the average user.
