GTA 5 has weathered the release of many a competitor over the years. Two Watch_Dogs titles, Mafia 3 and even Sleeping Dogs: Definitive Edition hit the shelves and digital storefronts since the initial release of Rockstar's flagship game. And yet, the sales and popularity of GTA 5 have only increased since, and all of the listed games reported fewer-than-expected copies sold. What's the key to this impenetrable defence?
Now, time and again we've examined the reasons for the game's success, so we're not going into that again. However, there is some correlation between the two phenomena. Certain key differences in spite of sharing gameplay foundations have prevented these otherwise heavily marketed and hyped games from making as much of a splash as Rockstar's hit open world title.
But first, for those of our readers who aren't too versed in the gaming world and stick pretty much exclusively to GTA 5 — how are these games similar? Well, all of them are open-world, all of them have a focus on organised crime, all of them feature the driving and stealing of vehicles as a major gameplay element, and all take real-life cities as inspirations for their settings.

Should you watch a gameplay video of any of these games, the similarities would be undeniable. All of the games are also major AAA titles which were backed my expensive marketing campaigns and achieved moderate to big success in sales — save for GTA 5, which achieved an insanely massive success.
So, wherein do the differences lie? Sure, Watch_Dogs has hacking, and the second game — which was recently released — makes non-lethal playthroughs possible. Sure, Sleeping Dogs focuses on melee combat and is set in Hong Kong. Sure, Mafia 3 takes place in a very different era. But are these differences really so important?
