1) I too dislike the stock music package within the game. I never listen to music while racing. Having the ability to stream your own music library as GTPSP does has been confirmed by PD for GT5 and I will appreciate it while watching replays only.
2) GT5 is said to be quite different in many ways from GT4 and it's hard to actually say what I will do first (other than wipe up my drool and pinch myself to verify that I'm not dreaming). There are many things included that we've never seen before such as sharing replays etc.
3) I will not be "forcing" any of the new features as many of you have stated. I want to experience the excitement of encountering the new effects spontaneously in the virtual racing world, not just wrecking the car for no reason other than to see what happens. I want to be surprised at the outcome of my actions during the actual racing.
As for the first driving experience, it is hard to pin point it at this stage. If we are allowed to transfer cars from Prologue and/or GTPSP, they will more than likely only be available in Arcade mode and I will get into something wickedly fast and do a few laps around the Ring for old times sake. Having lived with EA Sports atrocious Nascar series for so many years, I am really looking forward to some immersive Nascar racing and hope to God they include long races with pit stops and car adjustments
After installing the game, it's actually hard for me to say in all honesty what I'll do .... I just follow my instincts. Obviously, as many have already said, we will all have to go thru the settings and options.
When GT4 released, I played it for 17 hours straight and I doubt GT5 will be any different
At least I'm retired now and don't have to use a weeks vacation like I used to
