This really annoys me. The more I play GTA: O the more I realize how many more features were added in GTA O than its single player mode.
Like selling cars, arm wrestling, more customization of clothing, cops being able to detect stolen cars which makes your personal car more vauleable, insurance your car and being able to track your car, robbing stores give you more money, if you wear a mask when robbing a store and then if you take it off when you're outside it'll drop a star thus wearing masks actually have a point in the game, the RPG elements are more noticable because they ar harder to level up, and being able to pay for different apartments/safehouses,
What's up with that? Not to mention the heists planning in your own apartment. While I know the aspect creating your own heists and crew outside of the missions may not make sense within the story, and it'll be easier to make money but they could've program'd to be balance.
The single player really got booted in some pretty neat features strictly for online. But really annoys me is that R* just seems to purposely hold back on the single player, I know some of the features may be in DLCs, but they should already be in the game after seeing GTA Online. Plus despite the repetitive missions in GTA: O, some of those missions could've been in the single player mode and it'll extend the length of the game.
