For PAX East (and a few other conferences) we printed up game download cards as a promotional item.
Now that developers can generate their own IGS keys, I thought there may be times that they would want to use our card template to print out cards for conferences etc. You could even potentially sell your game cards at PAX and other game expos.
You can download our game card template here (Adobe InDesign):
We used Adobe InDesign, but all you need to do is generate and place your own game image on the card and then contact a printer that can do variable printing. You'll need to generate a unique IGS key for each card and save them all into a txt file to give to the printer.
If any developers need help, please let us know!
