Piratecraft is one of the most player-friendly creative servers out there, and an easy choice if you've ever thought the pirate's life was for you (yo ho, yo ho).
Whether you're building the biggest vessel on the seas or focusing your efforts on creating the best port there ever was, you've got a ton of space to work with in PirateCraft's creative mode.
Players get access to the standard 64x64 plot initially, but can accumulate up to 16 plots of that size. The admins encourage members to consolidate their plots into mega plots and build the most massive pirate world they can imagine as well.
There's a host of quality of life features to make that process easier, too, plus access to worldedit without jumping through any gimmicky hoops.
Should you wish to see your creation in action or use creative as a testing grounds, you can easily switch over to survival or PvP to see how your pirate skills match up to others as well.
Oh, and there's an instant parrot command that ensures your feathery friend is on your shoulder at all times. There's really not much else you could ask for.
