So I didn't come up with most of these, if not any of them, but I thinks some of these in the tower would be cool. A barber. Yes, people say they want to change their hair styles and magically grow a beard or a stache. A shooting range to test out our new gear and weapons, or just to mess around in. A sparrow racing course to test a new sparrow or race some friends and have a good time. More merchants. A merchant to sell materials like spin metal, helium filaments, spirit bloom, etc. we already have 25,000 glimmer, let's spend some! A camo specialist maybe? There could be a merchant that has some special armor shaders that give us a camo pattern on our guardians for different planets and what not. A library. We collect our grimoire cards and have to come to the website or app to look at them, a library would be great to read them at because this game's story mechanics are similar to a book's story, we read and play to unfold each chapter. This could be a great way to learn more about before the collapse, our enemies, and just more about the story and characters. Possibly a trading room. The trading system would not go over board, but you could trade materials that only go up to rare or uncommon. Trading legendaries and or exotics would be a little too much. Maybe an auction room, where guardians could auction am item or an AI could auction off materials or items that guardians could be drooling over just to get their hands on BUT, for a very big price. Some voice chat options so you could choose to talks to just your fire team or every player in the tower, or you could just talk to everyone in the tower but also have a mute button (for those annoying people that can't shut their mouths) so that we could get together and take on a strike, a mission, or do a raid together (since there isn't matchmaking) or just to take on other guardians in the crucible. I can't remember all of them, but these were some I found in the forum and I came up with one, but these could add some excitement and fun in the tower and also make it more social, it does say "Tower/Earth/Social" when you click it in the destination anyway.
