I played 1500+ hours on Civ 4 but only have 200+ on Civ 5. I thought Civ 5 was a huge decline from Civ 4. So I am very hesitant in picking it up. It being on Switch has made me think twice but it still is a sequel to Civ 5. Then again Breath of the Wild was a sequel to Skyward Sword and I loved Breath of the Wild. Maybe I will think about getting it later.
From what I saw from gameplay footage it seems to run really well. Civilization always seems like a game best played on PC but they made it work on Switch.
