This is a set of floor tiles. Normally, I would go with just 2x2, but sometimes it is easier to plunk down a few larger tiles on the table, and rare configurations leave a single spot open, thus the 1x2 and 1x1 pieces. These go with the other Gothic RPG Tiles I'm releasing here on Thingiverse, in case someone wants to print a full set that is consistent in style. They are normally used in RPGs such as Dungeons and Dragons or Pathfinder, or with wargames such as Hordes, Warhammer, etc.
