Warning for those who wish to download Gran Turismo 5 Prologue from the playstation store
To those who wish to play there game at friends or don't have there own Internet connection (or if you just don't find it necessary to be log in all the time)
I recommend buying the game in the store and not from the playstationstore.
Truly they did not think about people who don't use there playstation only at home. For people like me for which the playstation is my travel buddy who keeps me happy when in some hotel room.
The Gran Turismo 5 Prologue itself is indeed a good practice run for things to come and I can't wait for the real thing. I especially like the in car view though a wider view angle would have been nice. Though I love the online racing the single player mode just doesn't feel complete.
