One of the best things about Bethesda’s RPGs is their excellent replay value, and Fallout 4 won’t be an exception. We already know that even the game’s developers don’t know everything that’s in the game, and now lead producer Jeff Gardiner has come out to say that he’s still discovering new things in Fallout 4 even after pouring more than 400 hours into the game. Keep in mind that he’s only talking about the base game, which doesn’t include the future expansion packs and near-infinite player-made mods that are sure to come.
