That was the plan.
Generally I don't revisit old material, although I do new material along the same theme. For example my sister went on a trip to Vietnam recently and took some photos to make surface textures for me. Some of those photo I think will make excellent source material for a new set of Dungeon Map Tiles. Will have to wait and see what I end up making.
Planning more Sci-Fi stuff, even was thinking about a Dwarven Themed set of Dungeon Tiles. Had an idea for a Goblin Town set... but I'm currently polishing off a small Compass Point (called Grunk's Lair) which I hope to get into the Fantasy Grounds store.
Then who knows what I'll make.... although I am keen to make a bunch of Sci-Fi Furniture Tokens to complement the Sci-Fi map tiles.
Plus also I have stuff I want to build for the launch of MapForge too.
