I like all the biomes and I usually build connecting (by rails) bases in each biome so I can enjoy all they have to offer! It can take a while... but I love them all.
But if I had to pick a favourite its probably plains, I like the sometimes large flat areas for building and I usually build floating cities, as so trees, jungle trees or hills get in the way.

It is againist the forum rules to bump in this section.
I like plains and ice plains, easy to build.
