The billboards are awful. Inside the Towers shop I guess I have no objection, but outside I really dislike them.
After 14.6 went live, I was shocked when I came to the center gate in West Athen and saw the awful big billboard prominently on a building there. They still haven't grown on me since then; they still stick out like the blight on the landscape that they are.
One of the nice things about Clan towns compared to Omni ones was how much more of a simple, non-commercial life they represented. Beautiful, peaceful buildings.
Now with great big ads slapped on them.
If my Flamethrower of Zuwadza actually worked on them, I would torch them as fast I could. FIGHT THE OMNI POWER, FIGHT THE COMMERCIALISM THEY REPRESENT.
(... IRL coming from the State of Vermont in the USA, where billboards are BANNED.)
gives me a new place to sit
