The only problem I have with this, is that I know where the pirate ship is located. The secret cave is locked off from one of the castles in the game, and everything is in it, except for enemies, and the pirate ship itself. This is the same of the orrery as well. Also of note is that there's already a hidden crashed pirate ship in the game, in a cavern, filled with pirates, that you can find, if you're clever enough.

Anyways, I'm quite sick of being made to pay for content that was already planned for the game (by these empty rooms), and then kept out for the sake of making us pay.
That's like taking doom 3, and making us pay for hidden medpacks in spooky corners of the game, that would of been there normally.
