The expectations that games will be moddable and playable online are high for every release these days. So what happens when a popular game doesn't come with the tools to edit it? People band together and start hacking and providing the tools themselves! Grand Theft Auto 3 is hugely popular, and the only option of making any changes in the game are skinning your character. Aparently, that's not enough. Now you can model your own cars, and even build your own city! Incredible.. The implementation of the 'hacks' are not simple, and makes you wonder at what could be if Rockstar provided the support themselves. The results, however, really add extra longetivity to such a great game. Anyway, read all about it at 3d Action Planet. Oh yeh, online playability would be nice too. :)
