This affect sensefull answers greatly. It makes not much sense to suggest a Seed with only 20 (Iron) Cryptas if you want to play the map longterm with friends for example

I just want to make a big mountain temple in creative and use this as a base for a survival game wich I intend to use for a long time.
I want the island to be very big to expand my base down the mountain and hopefuly manage to build a connected network of small villages along the island, while still having large wild forests and meadows.
So far, the best seed i found was G4WUchvTE9
