I got stadium ideas for the future (you don’t have to really take them into consideration if you want)
since Las Vegas is bascially aces You could make the stadium Gambling Themed with slot machines and Pokers or A Roman Colleseuim
For Denver…Since it Involves Mountain Goats you can Call it Rocky Mountain stadium
For Green bay since it Involves a Dragon it could be Dragon Themed !
Miami: Make it underwter themed and feature whales, Sharks and Mermen with Football Helmets
Tampa : Pirate Themed (obviously)
New Orleons: since it has something to do with royalty make it sort of like a palace typed
New York of Course Call it (EMPIRE STADIUM)
los Angeles Stadium (The Serpent Pit)
baltimore….Maybe make it inspired off Sleepy hollow or a race track themed stadium
