Why have they not done this with 4e?
In fact, screw 4e. I want to see this game with blue-map era megadungeons, using the blue-map cartography and red-box D&D rules. I want APP ON THE BORDERLANDS! I want SECRET APP OF BONE HILL. I want RUINS OF APPMOUNTAIN. I want CASTLE GREYAPP!
Seriously, why can I not play turn-based party dungeon-crawlers with D&D rules and awesome graphics like this RIGHT NOW?
If you know of any, put them in the comments. Please bear in mind that I cannot afford cocaine or Apple products. Derek Proud of Dungeon Mapp - are you taking notes?
Incidentally, one day left on the draw to win a free copy of Dungeon Mapp for the iPad. Send me an email at kootenaymurph at gmail dot com if you want in!
