Red Dead Redemption 2 might engender feverish excitement and it might be the most anticipated game of the year, at least on the platforms where it’s got a release date, but Take-Two isn’t heading towards the game’s launch with expectations of Grand Theft Auto 5 levels of success. 

With sales rising to almost 100 million, Grand Theft Auto 5 is safely one of the best-selling games of all time, only outdone by the likes of Tetris and Minecraft. Despite releasing in 2015 on PC, it’s consistently on the Steam top-sellers list. It’s perhaps not surprising, then, that Take-Two aren’t predicting that Rockstar’s latest will beat it.
