I got a call last night from my FLGS, the Fantasy Shop in Florissant, that the GamingPaper MegaDungeon I had requested had arrived. After work today, I swung by there and picked it up (along with a few booster packs of Magic cards). That was $25 very well spent!
The GamingPaper MegaDungeon is 100 8.5"x11" sheets of dungeon geomorphs that are usable at the table, in game, for Fantasy Role-Playing Games that use 1-inch square grids for combat and exploration. It's basically perfect for building dungeons in 4E and 3.x D&D and Pathfinder. The sheets are double-sided, with one side furnished (thrones, crates, tables, chairs, etc), and the other side is the same map, just blank.
I'm very much looking forward to assembling some dungeons for my kids to explore. I will say this: these are a lot easier to use than WotC's Dungeon Tiles. I like the Dungeon Tiles, don't get me wrong, but they are a pain in the butt to assemble, quickly, in a usable fashion. This GamingPaper product seems like it will be incredibly easy to use. Each individual sheet is labelled with a letter and number (and a fully assembled map sheet of all 100 geomorphs in a 10x10 grid is included). I imagine I will be investing in 100 lamination sheets for them so I can draw on them with wet-erase markers.
Oh, and I'm thinking I may have to use these to really start doing some adventure design, so hopefully I'll have some dungeons up for you to use in the near future!
