Okay, I'm thinking this as a 1-30 adventure. :) I know everyone's down for epic airpirateness and we're going to start at that level.
But... do we want:
lvl 1-10: Countrywide pirate antics
lvls 11-20: World wide pirate antics
lvls 21-30: Interspace pirate antics
or
1-10: World wide
11-20: Interspace
21-30: Interdimensional.
31-40: Tenga Toppa Gurren Lagann
That's just going to be the epic finale anyway.
If we get that far. :)
Ehh.. I'm leery of going interdimentional on a new-ish system none of us have any experience in.. Also, I've never gone anywhere near epic, so..
I'm voting to keep it at interspacial. But, if the vote ends up deadlocked, consider my vote a swing vote to break it in favor of interdimensional.
