Pretty cool seeming game allegedly coming out at the start of 2017.
Here's everything I've compiled from various e3 interviews
The world:
-Its shared world a la destiny or the division. You'll come across other ships but you won't be crowded out like an mmo
-won't comment on specifics size but their goal is for it to be massive and no load screens or servers
-there won't be NPC ships but there may be NPCs at ports and stuff
-there will be quests, not all of them will be combat based
-there's bars, musical instruments, and "tools" for players to create their own bar games
Progression
-their will be a gold economy that you can find in treasure, sell artifacts, and steal from other players
- player progression won't be commented on
-player and ship customization (both cosmetic and functional) is confirmed
Other shit I don't feel like formatting
-confirmed weapons are swords and blunderbuss, but they were turned off during the e3 demo
- there will be giant monsters to face, one example being a kraken
-we will hear about the beta "soon"
