The Witcher 3 is as close to perfection as any RPG to date has managed, thanks to a dark, brooding world inspired by lesser-known myths from European folklore and a plethora of both rich characters and quests that suck you into its medieval world. However, with the series recently-established position as one of the great video-game franchises, its reasonable to expect - nay, demand - that its next outing not only irons out the few flaws of its predecessor, but breaks some new ground for the RPG genre. With the ink barely having dried on Witcher 3 reviews, the more respectful gamer may cry that its too soon to talk about The Witcher 4. But that hasn't stopped a shameless bunch of brattish fans from starting a petition demanding that The Witcher 4 be made - or me from thinking about how it could build on what the series has achieved so far. With developer CD Projekt RED currently focusing on sci-fi RPG Cyberpunk 2077, it'll could be a few years before we return to the Continent. But with the series having truly found its stride in its third outing, it seems inevitable another in this world - though almost certainly not revolving around Geralt of Rivia - will grace us one day. Here are the ten things that the next entry in the Witcher canon will need to do if it - like its forebears - is to become one of the greatest games of its generation.
