Thanks, BKK2. I have additional questions, since you seem to have answers 
.
1. How difficult would it be to make an assessment of attach rate for this game. In other words, how big was the PS2 user base when the majority of GT4s were sold, for example?
2. How much competition (good racing games) were available on the PS2 when GT4 was released?
3. Which of those other titles are "prologue" version as opposed to "add-ons" to a base title?
