The Blood of Dawnwalker, the new RPG from a team of former The Witcher 3 devs, offers such a free-form approach to its main quest that you can run right to the final boss at the very start of the game.
Speaking to the Future Games Show, game director Konrad Tomaszciewicz outlined the story of The Blood of Dawnwalker - playing as Coen, you'll have to save your family from Brencis, an ancient and powerful vampire, within 30 days. Fail, and they'll probably suffer a grisly fate - but it's also possible to speedrun the entire rescue mission.
