Paper miniatures are minis too. They certainly have their place here on TMP.
And they have their advantages. Let's say you need 30 skeletons. At $1 USD a pop (for instance) you get some DnD pre-paints and you are ready to go.
For far less than $30 USD you could buy a set of paper minis that would include skeletons, goblins, kobolds, etc. You print out a sheet of skellies and you are ready to go.
And if later you want a mob of 30 more, another sheet and you are good. And what about those goblins down the next hallway, or those kobolds to your right. You are a printed sheet away from having what you need.
Are they as nice as 3D metal or plastic? Not in my opinion. But they are ultimately cheap, and easily renewable if you need more. They are lightweight too. No need to store them in protective foam figure slots either. You could probably pour 100 of them into a ziploc quart baggie and not worry about the odd bent figure here or there.
Cardstock creations can be simple drawings that get the job done, and they can be wonderfully colorful and richly textured. Just check out
