-I think Ship liveries are a must & having the captain / crew name plastered on the side of the ship too adds that aspect of personality to the ship. Just general Decals (somewhat like elite dangerous)
-If not entire ship skins then nose arts would be a fantastic edition. Since the games dieselpunk theme, having some sick WWII dieselpunk-esk nose artpacks would be amazing, ideally make these skins big enough/visible enough/in the right place on the ship that the pilot can see them while flying the ship, nothing worse than a skin you can't see often. In my head, seeing a big mural of a kraken holding onto the front of a Heavy Frigate would be amazing, wouldn't mess with visual clarity that much.
-Non intrusive gun skins, ofc avoid changing gun models for skins (like Apex Legends does a lot)
- Maybe armor stickers, avoid allowing reskinning armor items cause it messes with visual clarity but being able to add faction stickers to your chest/helmet would be sick, just avoid full recolors.
A few extra voice lines / goofy voice lines
-simple emotes like dark & darker style stuff, point, hands up, etc etc etc.
-progress outfits are always nice, more of what we already have is a great place to start for ingame earnable ones.
-Wall sprays for general silliness / [crewname] tags, would be sick to throw up a tag on a wall everyone can see during a raid.
-Stat trackers that could be physically displayed inside ships would be amazing IMO, like "Times breached" or "raids since last breached" or "gun kills" or "fire extinguishers used" etc etc etc.
Breaching onto someones ship and seeing a big stat tracker on the wall that says "TIMES BREACHED: 93" would be mildly intimidating
-cockpit accessories would be sick, little baubles & bobblehead type stuff the captain could put around the cockpit.
