FOSS gamedev and creative worlds

Seed first (if you have a non-numerical value, like "seed" instead of "7433841846291520339", use the non-numerical one)
then mapgen (e.g. "mgv7")
then summary.

Include screenshots as attachments please!

I'll begin!

Seed: nyancat [mgv7]
Summary: A crazy mix of 3 inhabitable biome types: jungle, forest, and savanna, all can be seen right from the spawn continent. Also, there's a huge ocean which turns into a big swamp, dividing a big jungle-forest mix mountain island from the beach-savanna-jungle mix mainland. Not to mention the long mountain blob on the savanna part of the spawn continent. It is best to open up Minetest, create a new world with this seed and just have a look yourself.

Seed: gnu [mgv7]
Summary: Just a nice survival seed really. You spawn in a fine forest, water is really near so no problems with starting a farm here. There's also a jungle biome nearby, as well as a conifer forest on the other side of the river.
