Going Silverwastes I never get tired of the engine sounds of the airships above and the distant barrage of cannon fire at the fort across the map.
I can walk into the Priory tent and see detailed blueprints of the airship and pact weapon designs. There is a strategy table there that has complex warmaps of the entire zone and where the forts + airstrikes are happening complete with little plastic figurines.
You can go as far as to translate the krytan script on some of the designs and posters and actually read what they say.
Random NPCs have banter like the explosives demonstration that the Asura shows the Charr.
Truly a reminder that this is a quality game and always will be.
