Psyonix says unique things Rocket League Credits will be valued on their own terms and will differ from the distributed rules.
The engineer said it will discount players who spent credits on the underlying exorbitant costs, restoring the contrast between the old and new costs to their Rocket League accounts.
"For instance, buyers of Crimson Fennec will get 500 Credits back today, as a Crimson Fennec presently costs 700 rather than 1200 Credits," Psyonix composes. "This value change is a one-time just function, and just applies to buys made between December Buy Rocket League Credits 4 and December 11."
