Hello

My 'Digital Dungeon Rooms' Kickstarter is live, funded and has unlocked 4 stretch goals so far with 13 days to go. It features loads of highly detailed cool Oldhammer styled rooms inc. Sewer and Catacomb themes for your games. Take a look:

PS - if you're looking for giant 27x18" digital maps in more than a dozen Fantasy and Sci-fi themes, try my Meanders range. Kickstarted over 3 different campaigns (with a new one planned for Dec 2017) there are over 200 currently available, and each one is designed to fit with any other one so you can make huge sprawling areas in seconds with just 1, 2 or more. Take a look for yourselves, and please feel free to ask any questions.
