To be quite blunt, I am heartily sick of seeing this pointless bleating everywhere. Is not the point of Gran Turismo to enjoy the driving experience? It seems for many the point has become to "beat the game", in complete reversal of what has traditionally been the heart of GT games. By this I mean the quick fix attitude, the "I want it and I want it now" stamp-my-foot approach that seems, in fact, prevalent in all areas of modern life.
The GT ethos - enjoy driving, win some money while you're doing it. Buy a new car or two with the money you've won, go and drive them. Over time you accumulate more money and more cars and can take your pick on any given day and go for a blast... GT can be enjoyed for many years like this.
GT5 seems to have inspired the complete opposite attitude and now we have quick-fix power gamers who want 20,000,000 by the time they wake up in the morning so they can buy a classic car that they seemingly are not going to bother driving, whilst simultaneously reaching level 40 and getting a platinum PSN trophy.
And the enjoyment is...? And the achievement is...?
Reaching level 40 is supposed to take a long time so, you know, it feels like... well... an achievement.
Having 20,000,000 to spend on a Ford Mark IV is supposed to be a proud moment in GT world.
You should consider yourself lucky that Kaz and his boys and girls even listen to any of the 'feedback' from their 'consumers' given that much of it is in the same vein as the OP in this thread. "I don't want to enjoy GT I want everything now"... then shelve the game after a few months.
If you don't want to enjoy GT the way it was designed and planned to be enjoyed (and indeed is by many many long time GT fans) then don't... but please, please shut up about it. Doing a few 5 lap races, 2 hot laps and winning 5 million credits is ridiculous and I'm quite glad they've ended it. The phrases 'rubber-banding', 'grinding' and 'duping' are a sad indication of a very demanding and impatient culture and should, in my view, be stricken from GT vocabulary and consigned to a dusty and forgotten corner of our minds.
