I read somewhere that a lot of the starter cars in Xtreme used to be available for Credits, but now they cost Tokens only?

Granted, the costs are not too high but Tokens are much harder to come by and it will take much longer to collect cars since the Tokens don't really get given away much in prizes. Even the Credits themselves don't count for much, since every race pays you so little.

Then there's the fact that the cars always need an oil change like @Dodensportaler43 said, and your oil consumption depends on the distance/number of laps you drive. So you can use the car more often if you only do 1-Lap races or you keep quitting before a race ends.

To add, a Fandom User stated on this wiki that the game itself can't be played offline? I can't confirm this since I don't have Xtreme but this was reported as of December 2016.

All this on top of changing the oil all the time and waiting for the process to finish, or in other words, it's Gameloft's way of discouraging players from playing the game for long sessions.

The added reports of people randomly getting banned and the serious monetization of this game have stopped me from ever downloading it
