Anyway here are the features I'm looking forward to making the HUGE assumption they
A. Are even going to even be in the game so far the only video evidence I've seen is for ship to ship and mounted combat.
B. Are going to be anywhere near "quality" material. In short it has to be fun, content for the sake of content is worthless.

Here's what I'm hoping for in order of greatist to least.

1. Skill system. I really am hoping for an orginal and interesting skill system. Not much hope for this one because the Devs say every skill has a max out of 100 points. Meaning either its going to be super fast leveling or its going to be some sort of grind between points.
2. Combat. Simple one here must be fun and must be balanced there should be no GOD skills or style that you have to have or your owned.
3."Smart" Npcs would be awsome, probably won't happen.
4.Gank free areas, think Booty Bay gaurds on steroids you poke somone and you die a grusome death.
5.Player made towns, fortresses, we shall see there.
6. Ships and housing for players. The ships in the videos the devs released looked pretty lackluster so its low on the list.
