Here's a list of some of them!
As for some other things, there's Red Beast Energy Drink advertised on banners, Paragon City Pizza (Made Fresh By Made Men), and there's a new seafood chain that has a billboard in Talos Island, just above the PPD station.
You know, I meant to actually compile a list after completing this list. I often get hit my real life and an abundance of ongoing projects though ^^;
There are a lot of in-universe brands though, mostly shown through storefronts and billboard ads ^^ As I have work I'm doing on a few projects I'll try not to obsess over this right now, but may be back at some point with lists!
So I'm thinking of writing a dumb little CoX story, and while I was thinking of locations and stuff, I began drawing blanks on brand names. CoX has lots of in-universe, fictional corporations Like Crey, Aeon, Portal, etc but lesser known examples of day-to-day businesses.
For Example:
Up-n-Away Burger
Icon Costume Retailers
I know there's more. Is there a fictional coffee chain like Starbucks? What's that Donut place in Faultline called? what about those locksmith ads I keep seeing in the Rogue Isles, or that one drink you can get in Praetoria that's supposed to make you a docile loyalist or whatever?
Let's get a list going!
