A former Rockstar Games developer has revealed that one of the "hardest technical challenges" during the development of GTA 3 was due to the PS2's memory, which is why the player wasn't able to fly planes outside of a brief trip in the Dodo.
It's not often that we get to look at how big triple-A games are created (shout-out to Naughty Dog and Double Fine for providing some of the best looks at game development), but one of the most infamously secretive studios is, without a doubt, Rockstar Games.
Despite making some of the most well-known titles in the world, Rockstar is incredibly private and tends to do things in its own way.
As a consequence of that, there are a lot of secrets and mysteries surrounding the development of most of its games (just look at how we reacted to a single audio blooper being found in Red Dead Redemption 2).
That's been somewhat changed over the past few months thanks to ex-Rockstar Games developer Obbe Vermeij (who worked as Rockstar North's technical director).
