Today Mr UPS delivered my very own shiny copy of GT 5 Prologue Japanese Edition.
Sccchuweeet!
It is busy installing as you read this - yes, Installing - after you insert the BD and click ok through 3 Japanese screens (the only english letters are HDD) I guess you are being told the game needs HDD space, then it says you have enough HDD space then it tells you its about to use the HDD space.
After the install is done, and after I play around with it for a while, I will report back.
Later
