With how popular (and profitable) Grant Theft Auto Online has become over the last several years, it's little surprise that developer Rockstar Games released a subscription service. For a monthly fee, players can sign up for GTA+ and earn $1.5 million in addition to several other in-game rewards and access to a few games in Rockstar's back catalog. Recently, it was discovered that Rockstar has bumped the monthly fee up slightly and without much fanfare. This may be in anticipation of more fans diving in when Grand Theft Auto 6 launches, but it has been noticed by eagle-eyed fans who are less than happy with Rockstar.
