As well as my first game of 7TV on the weekend I also played a game using my (first time developed) super-villains. I originally had the characters printed on A4 sheets via Excel but they proved pretty crappy so I made some character cards. Like all the cards I'm making I tried to keep them in the same flavor of the game.
I made a nice little template on Photoshop that I can use over and over. I just change various cosmetic stuff like borders, colours, fonts etc... depending on how I want it to look - In this case: Like a comic book panel.
