I liked Civ2 very much...but I simply love CivIII! Easy gameplay, decent AI (even though the computer will cheat at higher difficulty level), good interface. It now matters which civilization you start with: All of them have unique units that, if used wisely, could make a big difference in the game. The new way to trade goods will impact your strategies. Of course, being to use a random map generator makes this game's replay value more than interesting. Only the lack of multiplayer prevents me from giving it a 10.
