Yes this game needs a trainer, and yes it should have a credits option. It should have as many options as CH Folks can make for it just like all the trainers they make.
If people are worried about getting banned from online play for using a trainer, there is an easy solution. Don't use a trainer. Just because it exists doesn't mean you must use it.
As for the rest of us that don't care about online play or just don't care about being banned in general... Train me up baby! I want ALL THE CARS!!!
" yes it should have a credits option"
So you can spend credits and buy and unlock cars with your internet unplugged?
Just making sure..
best,
