Although I’ve finally reached level 50 this week, I have no real interest in the engine swapping glitch exploits way of cheesing credits. But what I’ve been doing whenever I have a few hours and a need for a cash injection are a variety of races in a variety of cars, to make it feel less grindy. Most have been mentioned, but to summarise;
The WTC 600 at Tokyo: 825k credits (about 30 min)
Circuit De La Sarthe WTC 700: 825k credits (again 30 minutes)
Sardegna WTC 800: 727k credits (25 mins)
Then there’s the WTC 800 1 hour at Spa which is theoretically 1.5mil credits. Only attempted this one a couple of times but each time lost the CRB somewhere. I’ll get it one day!
And finally I like to do the final championship too. I haven’t timed it but I’d guestimate it takes about 45 mins? Could be wrong, and a theoretical 1mil from here with full CRBs, although again I haven’t quite managed this yet.
With all that and providing you do everything perfect you’re looking at nearly 5 million for 3.5 - 4 hours. But even if you miss some of the CRBs it’s a very lucrative Saturday afternoon well spent!
Not as ‘efficient’ as the glitch exploits maybe, but I dare say a lot more challenging and fun.
Also as has been mentioned, the circuit experiences. I really have to be in the mood to do these but they are very lucrative, even if you just want to plough right through and get the bronzes you’ll get 150-300k per track in no time and really easily. It’s worth getting the golds for 1mil + though, and the permanent boost to your quick races payouts, but it can be a very frustrating time sink (in my experience, at least)
