GTA 5 has once again gotten a temporary price cut to entice the ever dwindling number of gamers who haven't jumped on the bandwagon to do so. In spite of initial launch having occurred 3 years ago, Rockstar's open-world juggernaut of a game is still among the most popular being played today.

GTA Online trumps other high-profile games which are considered to be among the most popular franchises in both sales and playtime. Halo 5, the most recent installment in the insanely popular Microsoft exclusive shooter franchise has only a tiny fraction of GTA Online's weekly individual player count. Microtransactions in that game are really far from even breaking the $100 million mark in terms of income, while Shark Cards have long since passed the half-billion mark.
Only other ludicrously popular games, which get most of their players from the non-gamer crowd, like Call of Duty or FIFA can rival the success that Rockstar's game has garnered. Even so, sales are pretty steady. Naturally, they're nowhere near the numbers of the first year, but still, countless people are buying copies of GTA 5. It is among the top sellers on Steam, several online distributors push marketing for the game due to the demand, console marketplaces feature it continuously. For some reason, people keep buying this thing.
