Game modding is no new thing, but in recent years, machinimas - that's games that are essentially like short films using games as a means of storytelling - have become increasingly popular.
In fact, a lot of multiplayer games, RPGs, and sandbox games now come with either a Photo Mode or a Movie Mode that effectively allows players to preserve their antics or stage their own elaborate recreations.
This, however, takes it to a whole new level. The YouTube channel Kramer's Media has managed to recreate 1992's Terminator 2: Judgement Day in Grand Theft Auto V. While they left out much of the nuance and drama of the film, they basically replicated the action sequences which make about half the film.
In other words, you've got the opening future war sequence, the chase with the truck through the LA River, Linda Hamilton breaking out of the mental asylum, the assault on Cyberdyne Systems and even the bit at the end when T-1000 is shattered into a thousand tiny pieces.
The only catch is that the dialogue is in Russian, but it's still impressive nonetheless. Take a look.
