Recently almost all the new maps are 50 territories or less i just want to know why are there so many tiny maps.

as more people are starting to make maps, they make small ones to begin with, because they are easy

The small maps are easier (and faster) to make

I've actually noticed several people are planning or are in the process of making large maps. But there are lots of small ones for the reasons Arun and Grzechooo mentioned.

nate, try making a map, then make the questions

u did... well, u should already know the answer
