Dumbass taxpayers fell for it again. Yet another arena fully subsidized by the public dime, and no benefits aside from "tourism revenue" - as if this would not exist without the taxpayers giving billionaires a free billion dollar arena. Anyways, due to the amazing cost of the arena, it should absolutely include a full suite of amenities tailored to player comfort - world class gym, spa, nutrition center and player learning facilities. as for the name, it needs simply be called "The Forge", the district can be appropriately named the "Slag" or even the Slag Center. The arena district should have a lot of bars with ample patio space that can be covered during the cold ass winters so the space is still usable. As for location, it doesn't really matter because all of Philly is basically a shithole anyway, so one close to the mafia protection rackets, so that there is a good amount of protection and things wont go sideways is probably the best location we can scout for.
