In short: Bethesda has not talked too much about what will keep Fallout 76 players in the game in the long run. However, Deputy Director Emil Pagliarulo discussed the last advance, some of what Fallout 76's endgame would mean.
Fallout 76 is less than two weeks from launch, but we already know a lot about it. One thing we do not know is what endgame is going to mean. Each MMORPG has a hook that holds discs interested and plays long after they have the maximum character.
Bethesda has previously suggested that endgame in some way involves nukes, but the question remains: How does nuking each other increase the life of the game? The studio revealed a little more about it on a preview show in West Virginia last week.
Most MMORPGs have something that keeps players playing even after they have mastered the core of the game. Generally, this will involve things like dungeons and raids with super powerful bosses that need to be taken down by several players. The reward is usually rare weapons, armor and objects.
Venture Beat participated in the preview event and learned a little more about Bethesda's hook for high level players and it's not like other MMORPGs. There is no raid – there are no dungeons. There are caves you can explore and it's expensive to fight in them, but you can still solo them if you want to.
So what's the deal? What's going to keep people playing?
Endgame is called down to what Fallout 76 Design Director Emil Pagliarulo calls "reach loop". As we already knew, players can collect launch codes to put off warheads. Once an area has been nuked, a few things happen.
"When you get to higher levels and you can get necklaces and actually put one off, what does it change the region as you enjoy a high-level zone," said Pagliarulo. "The creations glow. The flora is different. This is where you can get some of the highest levels of recipes and ingredients to make the best weapons in the game. We see it as a repeatable content loop. It's the big endgame content." 
Unlike Fallout Games from the past, most of your equipment will be made rather than being found. Although Fallout 4 had a good design, it was first and foremost modding existing equipment. It will be different for 76. Remember, these are the first whalers who come after the war. Everything is broken and they (you) need to be rebuilt from scratch.
Recipes are the primary means of obtaining weapons, armor and other objects, and there are about 700,000 different hand-held items. You can expect that the drawings in the nude zones will be more powerful, but also more dangerous to retrieve.
Will this be enough to keep people in the long run? We must wait and see, but Bethesda has suggested that it not rely solely on end-game play for longevity.
"[The development team has] talked about future expansion-type things," said Pagliarulo without going into detail.
Fallout 76 hits PlayStation 4, Xbox One and PC on November 14th.
