The first film, The Gamers was a loveable low budget knowingly self-mocking film for D&D players, by D&D players that did the convention ciruits some years ago. Now, armed with a budget for some better special effects, the hilarity continues.
The story? Well, a bunch of the usual suspects play D&D, only to make up numbers, one of them has to rope in an ex-gf.
If you know you will get the in-jokes, this one is definitely for you. A great popcorn movie.
