Burnin' Rubber, by Ocean, was a game that was included with every 464+ and 6128+ on a cartridge, in a bid to showcase the CPC+ new abilities. Therefore it was quite popular, although it did not really show off the CPC+ capabilities, being an early title and all. Despite that, it wasn't a bad game on its own and is considered one of the good racing games on the CPC.
