Choose Seeds similar to where you want to Spawn [Islands, Terrain]

The idea is to not make it so that you can spawn in specific biomes because I feel like that might take away a bit of the creativity to having players make do of what they can in those biomes.

But I feel like a setting to help pick your seed may be okay. For example, generating near islands. Perhaps you will spawn on Island or nearby some. Maybe choose some really flat land nearby. Etc and you can sort of choose how your seed is going to be picked.
