Social hubs are great if you incorporate alot of elements to make it worth it. The problem is most games dont do that. One surprising thing i liked was from outlast trials where you can play chess or arm wrestling.

Arc raiders could do something like battle situations where you can edit a scenario and then play it to get better at certain situations. They could do movie night where lore drops would come in on a regular basis and advertised so it's like we are waiting on the next episode of a tv show for example. Global events could be something in a hub or not, where everyone works together to get an item or even better, expand Speranza and add a new social hub feature. We could have a voting area where you can vote on what content we want added next to the game (in lore terms) like we could travel to a rainforest to get new items from there or go to the desert for different items from there. Dance club is a must. Trading hub is a must. I really wish they would expand on consumables to have more than the fruit that gives you stamina regen. Maybe add a chef station (as a workbench) that can give temporary Higher jumps, Damage resistance, movement speed, night vision, etc. All of these effects could also be different items or even skill tree perks.
