All the things you love about GTA V. All the things you love about role-playing video games. Together in one place. It's slowly happening, all thanks to a person who doesn't work at Rockstar.
GTA: RPG is the work of LogicSpawn, a modder out of the UK who's doing the hard work of adding skill trees, new contracts and dialogue interfaces to Rockstar's giant open world sandbox. You can see some of it at work in the video above.
While some of the interfaces and text are still rough and in development, it looks like LogicSpawn's work might deliver on the hopes that many GTA players had for the game's online component. While, the official version of GTA Online does have some RPG-style progression features, they're pretty shallow compared to depth of systems typically found in the genre. With GTA: RPG, PC users will be able to pick a character class, focus on specialisation and go on sidequests. If you're interested, you can grab the mod here.
