I have one save file with the glitch and another without. I really enjoy earning the credits to purchase and modify cars, but when you consider how low the payouts are (even after the 1.02 update + log-in bonuses) and how infrequently the seasonal events are updated, it will several hours of non-stop grinding to earn enough for just one of the 20M cars. Multiply that by the number of 20M cars and you're looking at DAYS of accumulated time grinding.
It would be one thing if the career mode contained enough content to earn the credits through natural progression, but this isn't the case. So the two options available at this point in time are: A) grind the same high-paying races repeatedly for dozens of hours, which is an absurd amount of time for what is essentially an imaginary car; or B) complete the seasonal events as they are released, which would take over 12 months at the current rate at which new seasonal events are released, and I simply don't see myself staying interested in GT6 for that long. Of course, both of these scenarios assume zero spending on any other vehicles or tuning, which would only emphasize the monotony of it all.
It seems PD has taken a similar approach of so many online shooters, in which players invest dozens of hours leveling up and continue to play the game for many months. Unfortunately, GT6 lacks the content to remain interesting for that amount of time.
I used the exploit to acquire exactly enough credits for the six 20M cars I wanted so I had exactly 0 credits left over. This way, starting from zero, I can play through the game and earn credits to purchase vehicles I want without having to invest an absurd amount of time to acquire the few 20M cars I wanted. I'll probably keep both saves and see how the game develops over the next few updates. If content is significantly increased or payouts are raised again, I'll probably go back to my save file without the glitch; otherwise, I'll just keep my cars and play the game as I see fit.
