It might be naive, but then again I don't think games development has ever been easy. I'm constantly amazed by the skills of games devs, they just seem to surpass anything done for business applications.

If a company wants to attract competitive gamers, then they have to develop games you can't cheat in during competitions. Right now, the most reliable way of doing so is server side, with all the challenges that entails. Otherwise, they have to install what essentially amounts to rootkits - which isn't exactly what most gamers want to encourage.
