There’s some bad news for those who still enjoy receiving free monthly PlayStation 3 and PlayStation Vita games on PlayStation Plus: Sony has announced the service will no longer include PS3 and Vita games come March 2019.

The current six-game offering which has been the norm since the launch of the PlayStation 4 was released in November 2013 will see its final month in February 2019. After this, Sony will only include two PS4 games in its monthly lineup and nothing else.
