Fantastic
I'm a big fan of Roman and Greek War Galleys, and a big fan of paper models. Eric Hotz, illustrator and artist for
Columbia Games, also has his own paper building and modeling company,
Eric Hotz Artworks. He has recently released a largish line of variably scaled Roman warships, called ROMAN SEAS. The models are low-cost (compared to metal), reusable (buy one model, print a billion copies), and relatively easy to make by all reports.
There is also a pack of accessories, shipboard stuff like corvii, but also harborworks, villages, lighthouses and such. All primarily in 1:300 scale (but scalable up and down to other scales).
I'm cautiously optomistic... heck, ten bucks a pop is no big investment to find out.
