Oops, my b, misunderstood. I prefer civ V, and seems like a fair number of people do too. I like the art style, and game mechanics better in V. Admittedly though I could never really get into VI, but it seems like a lot of people prefer it too.
This is a fantastic documentary on Tetris by Gaming Historian. Fascinating history about its development in the Soviet Union and how it came to be a launch title for Nintendo.
