Now that we have Gamer, here's the other viable option.
Everyone would fight on the ship. Captain Wario and his minions are still there. But this time, Wario is directing his orders towards the players. He's telling his minions to fire at the characters he names.
That would be pretty neat, but what about the dancing sequence?
Can't have a pirates stage without that, I'm just wondering how that could be includet...
I'd be nice to see it, if only for one more stage with an actual Wario theme to it. But to be honest, I think a general Diamond City or even Wario Land stage would be better.
What would a Diamond City stage add though? I just can't see it not being anything like Onett or any Animal Crossing stage. (i.e. a really boring stage)
Maybe if that sandbox game I mentioned earlier was made, I could understand its inclusion better.
