>why would you pay for an online streaming game service when you already own consoles or a robust PC?

Lots of reasons come to mind, but the biggest ones for me were portability (playing my games at max settings while traveling, at friends' houses, at work, at coffee shops, etc), the ability to play on whatever device I wanted (usually laptop or TV depending on the game when at home, but I also played a lot on phone/tablet while travelling), and to a lesser extent some smaller perks like using less battery life / hard drive space / time updating / etc than the native alternative.

In other words, if I have the choice between playing the same game on my desktop (strictly in my office) or on the couch (or wherever else I want to be), I'm always going to pick the latter.
