Cyberpunk 2077, by the same people who brought the Witcher series including the highly regarded Witcher 3 into Gamers hands, has been working on their new RPG based on the popular pen and paper RPG setting Cyberpunk originally written and developed by Michael Pondsmith.
It's planned to be an open world (in a city setting of course) first person RPG. CD Projekt Red has been developing the game for years, with it originally having been announced way back in 2012. It's release date has been postponed twice this year but has apparently entered its final certification phase with a planned release on November 19th, 2020.
The core game isn't expected to be as long as The Witcher 3 but will apparently have between 50-60 hours of gameplay and the developers are planning on releasing more DLC for this game then they did with the third Witcher game. It also still offers Keanu Reeves presumably as an NPC character.
