I'd love a Witcher 1 remake - while the first game was super jank, it seemed to improve as you go, and had some real unique ideas that set it apart from the myriad of other medieval western RPGs. The Slavic fairytale influence in the later chapters, the interesting detective quest in chapter 2, the way the villain was introduced and how you effectively 'groom' the villain. Much improved battle system, fast travel, less filler quests, expand on a few story details, less backtracking through that goddamn swamp...
