EVE Online is a bit like this.

There's a limited amount of building that players can do, but some things like space stations and large ships can take dozens-hundreds of players to create and maintain, and battles over them can span days-weeks.

It comes with downsides. Even mid-range ships are expensive enough that their loss will sting low-key players, and nowhere is truly safe. It's also possible to trade game currency to offset the monthly subscription costs, so well-off players can offset their losses with cash.
