From the announcement:
We're a Kickstarter staff pick!
And we're celebrating with exclusive Titan Series box art!
All Titan Series backers at the Muse, Titan, and Mt. Olympus levels will now receive exclusive backer-only box art. World-class artists Echo Chernik (Shadowrun), Larry Elmore (Dungeons & Dragons), Andrew Hepworth (Exalted, Love Letter), and John Kovalic (Munchkin) have already been recruited, and we're looking to our backers to see what other artists they'd like to see join the Titan team.
If you haven't joined the Titans, back today for your chance to help us create the Titan Series and receive the games at nearly 50% off the retail price! Backers will help us tweak gameplay, select themes and artwork, and create game content. In short, this may be your best chance to work alongside some of the industry's greatest talents!
