There's a reason it's missing a lot: this is only the second game of FIVE, and the FIRST with that hub area. It exists a. for intro story purposes at the beginning of each game, but b. to gradually get filled in with extra stuff as we go on. That boar encounter being the first of many similar side things. To be clear I'll never have full-on elaborate side content coming off there, but there will be additional scenes and stuff going on in the hub as we move forward into the other chapters.
