The original Civ was a huge part of my early gaming years. I poured an insane amount of hours into that game. Civ II is imo the best in the series, or at least of the first three games (I didn't put many hours into IV or V, and I haven't played VI). Civ II all but perfected the formula of the original.
I actually had the Windows version of Civ which was slightly easier on the eyes and allowed you to resize and move the main, map, and status windows on the screen. I can still recall all the sound effects and music for each civilization/leader.
