A lot of good points have been made in this thread, however I disagree with the sentiment that once a race has been gold that it is time to move on. These races are enjoyable to do again, this is not grinding but enjoying the driving of the cars available.
This would only hold true *IF* the AI in this Beta release was not broken :-(
How can anyone here actually say they enjoy doing any of the races in the offline game when the AI cars just change line and just try to smash you off the track all the time? Or slow down to allow you to catch up?
The AI in GT 5 was many magnitudes better. And the races I used to love repeating were the ones where when you turned the PP down on your car to win more money and the real challenge was to see how far you could go and still beat the AI.
Sorry but no one will convince me there is anything enjoyable about redoing any of the races in this game :-(
I haven't even mentioned how there are no penalties and you can cheat as much as you want either. Nah! The "Real driving simulator" is badly broken in this Beta incarnation and the whole joke of game is just a pathetic arcade fiasco :-(
The only slight entertainment I have found with the grinding now is by how much I can cheat in the RB standard challenge and win by. Like how early can I ricochet to the lead and by how much I can cut corners by to win by the biggest margin possible. Like Mt Fuji and GP-F I am first at first corner. Silverstone all the corners I can cut and my biggest winning margin is about 36secs.
My only regret is that I didn't do the money glitch before it was patched :-( I had this (ridiculous - in hindsight) notion at the time that I would do the game legitimately and not cheat to get my Platinum (which only took a week except Autobarmy)
Grinding is not fun, this game is enjoyable offline and only barely tolerable online.
*IF* the GT5 servers were not being shut down I would be suggesting to all my colleagues that we return to GT5.
