I'm 47 and have been playing since Civ 1 for DOS (on a 386 with 4 MB of RAM). My 2 daughters, now in their early 20's played it then too and still play Civ 3 today. I love it because my job is sometimes incredibly boring and Civ forces me to use my brain and think! I will be playing 'Civ 9' in the old-folks home someday!
