11. Open All Interiors
https://www.youtube.com/watch?v=BKJGxBseSMA GTA V is a damn great game without a doubt, and I would even rank it as the strongest installment behind San Andreas. But if there's one thing it could be faulted for, it's a deficiency of interior locations - especially in comparison to the surprisingly varied interiors of GTA IV, which had you bouncing between projects, federal buildings, sleepy suburban homes and dingy warehouses. And although GTA V did a wonderful job of utilizing a smattering of impeccably crafted interiors in some truly incredible missions - the LifeInvader offices, O'Neil farmhouse and FIB building all come to mind - it would have been nice to see a bit more, or at least allow players the option of revisiting some interiors. With the 'Open All Interiors' mod, you can now return to some of the aforementioned locations, as well as a few that weren't included in the finished game. The FIB Building, the Union Depository, Lester's house, the Paleto Bay bank - it's all here.
