-After I generate some worlds. I'll post the results.
Ok, I generated some worlds with "1121" and the results was:
1st generation: A desert with some trees around.
2nd generation: A dry-ish forest. (the grass looked a bit dry, but warm)
3rd generation: A desert again. (with some trees)
4th generation: Pretty much same as 2nd.
5th generation: Pretty much same as 1st and 3rd.
END RESULTS: This seed gives dry but warm worlds.
Using the same number, I got a mixture of desert and barren fields, with a lot of exposed clean stone as well.
