That's fantastic: Sony found a way to ensure a "level playing field" for new games. The more popular it is, the more it costs the developer to demo it. That pretty much guarantees that anyone competing against SCE/Polyphony will get dumped with huge charges, while Sony can pretty much release demos for free. Nice job, Sony. 👎 👎
...And the sad part is that if this is true, we'll probably never see many 3rd party demos.
For now, I'm not going to pass any judgement until this is cleared up.
