I'm assuming is will be loosly the same as Toontown. But with a pirate theme and slightly better graphics annimations
Toontown has skill classes (drop, squirt etc..)
Toontown has mini games
etc. etc.
It rather seems that way with all the new info and screenshots.
But seeing as its based on the ToonTown Engine, then I'd be leaning towards it being slightly the same game feel.
