I played Civilization for years. When Civ 5 came out, I was incredibly psyched. I specifically went to PAX one year just so I could get new information on the game. When I finally played it, it was the biggest disappointment of my gaming life. It just doesn't feel like any of the previous ones. Civ 6 is way better in almost every way.
I'm wary of Civ 7 though. How can they improve upon the game without adding minigames or breaking it into insane amounts of DLC eg. Stellaris? I probably won't pick it up until it's on a steam sale with all its DLC at 50% off or something stupid.
