Honestly, it has to be a translation flub. How could it possibly work as an online game if you have to buy every car you want?
People will choose many of the same cars, like supercars, race cars, favorite sports cars and the like. But many of them will be drastically different. Some will choose a load of Japanese sports cars. Others will choose American muscle or European cars. How could this possibly work online? Almost every single garage would be different. Almost no one would have the entire car list. It would be utter chaos.
Fans will riot. Many will refuse to buy any content at all. It would be a huge financial disaster.
I know that some bring up Half Life 2 and its ridiculously short episodes sold for $20, good for all of 10-15 hours of play. Rather than rant about it - which maybe I should do at a Valve board - I just ignore it and wait for a compilation pack or something. Which, if Sony pulls this kind of stunt, I'll do with all of you guys.
One thing that did occur to me which would be quite sneaky but not too expensive would be to base the content of GTHD on whether or not you have GT4. Like if you have the game, you put in the DVD and it populates the car list from the game. It would require people to buy the Greatest Hits version if they don't have GT4 already, but that's all of $20 new. Then GTHD could be sold for $20-30 itself. But this is just idle speculation of course.
Fortunately it seems everyone has calmed down from the initial explosion from the leak. It's just over 24 hours till the big show, so hopefully we'll get a big heads up on what the truth is. But I can't see Sony going that way with any game. Just imagine Metal Gear Solid 4 sold as a shell with nothing in it but impressive empty cities and jungles to surf cam in, without a Snake to be seen anywhere in the world.
I know that Sony the megacorporation is a stinker, and I do indeed despize them along with Microsoft and EA, but Sony the game division seems to be learning from Sega and Nintendo that you have to be gamer friendly, so I frankly don't believe all this. I could easily be wrong, and if I am, I'll just go back to GT4 and Forza.
