Good idea.
I enjoyed the movie. Zombies always work, of course. There are only a couple of components you could work on to make this that much better. A less important one would perhaps be shifting the view around a little bit. Get a little more interest going with the pictures to go along with the story. Flashbacks to drawn clips of the game being spoken about would have been very nice to elaborate on the 'problems' of it. The main issue here would be the lip synching. It's quite important, especially for flashes based entirely on speaking. It made it difficult to watch, despite the humor and information presented. The end was very funny, the sound quality itself was very good, and it's context appeal should go over well. Good job.
