5. Submarines: Not Always Useful
For a game with a smart engine - about as smart as we're likely to see on this current generation of consoles, that's for sure - it's surprisingly simple to completely confuse GTA V. All glitches and mistakes aside, it is these possibilities that offer the most insight into the broken elements of the game: and probably account for all of the issues Online players had with disappearing cars and characters when the soft launch almost spectacularly imploded in Rockstar's face by simply refusing to work at all. The most comical example of a confusion exploit comes when you're exploring the undersea portions of the map in a submarine, like some fish-obsessed James Cameron looking for more old ladies' necklaces, stumbling across sub-aquatic Easter Eggs like there's no tomorrow. If you exit the game while using a sub, or if the sub was the last vehicle you were using before swapping characters, there'll be a spectacular, but completely useless submarine parked outside your safe house, or just randomly dropped nearby next time you return to the character, as if it's the most natural thing in the world. You might be the toast, or scourge of your neighbourhood for somehow magicking a giant piece of ocean tech into your street, but there's nothing you can do with the sub once it's there, apart from posing for smug selfies...
