Would be playable if not suffering from constant "random" events that are not exactly random as their outcome is determined by seed in your save file and no reloading generates new one. So you might lay nice until your leader dies, his son dies next turn because he falls ill and all your country falls in ruin because RNG had bad day. Not to mention that at some point events are just overflowing and more annoying than adding flavour.
A civ game is like a job program - its full of numbers icons and what you see in store images is nothing what it is in endgame or midgame. An old world game is as beautiful in early game as in mid or endgame.
Music in old world is quite a letdown - random sad, church music. They havent hired anyone to make a music for this game(according to my knowledge).
You can play this game without people! It can be disabled. You can also make 1turn not one year but 1 semester! Very awesome feature.
Game is quite charming.. It feels like a video game rather than just calculations and numbers.
