How long does an object need to be out in the wide world before it can be considered ‘retro’? I was recently privy to a conversation that dared to suggest the PlayStation 2 was now a retro console. I was having none of it. This latest release from Ratalaika Games, Cosmos Bit, available today on Xbox, PlayStation and Nintendo Switch, is a modern game with a retro twist. Harking back to the 8-bit platforming titles of the 1980s and ‘90s, can a new release be instantly retro?
