Some little while ago there was a thread on the RPGNet Roleplaying Open forum which posed this challenge: photoshop the cover of an RPG that doesn't exist, but should... or but shouldn't. Here's what I came up with:
In case you're not familiar with it, the two sources for this image are:
All Flesh Must Be Eaten
a creepy roleplaying game of zombies
Wallace & Gromit: Curse of the Were-Rabbit
the full-length feature film of the hilarious claymation duo
I was pleased with the idea, but surprised at how good I did at the photoshopping. I had to painstakingly separate the creepy inner image from all other elements of the AFMBE cover including the letters, which took a couple of hours; then make a capital C by extending a lower-case E and chopping it up; then rearrange the letters; then trim and size the W&G image to fit; then airbrush out the "from the creators of Chicken Run" and a few bits of the stem that they sat on; then merge the die and logo images; then align the letters to fit the image; then, finding the original reddish color disappeared too much into the pumpkin, remove them and recolor them and then place them. Total time, about five hours.
(Hopefully you know enough about Wallace to get the joke.)
