The whole point of the game is that it's turn-based
Yes except for the fact that a lot of people decided/discovered they hated
Civilization II multiplayer. It really didn't hit anyone how long/boring waiting on human players would/could be until you bought the game and waited...and waited...and waited... and then inevitably someone would bail (sometimes the server operator) and you had been playing all that time for nothing. Granted, some people loved this but for the others perhaps turnless would work...
