Yes. I played for 74 hours so far, which is much better than what I get out of most games. (In fact I paid EUR 55, which is a fairly normal price hereabouts, and I generally consider a game worth this sum if it provides me with 30 or more hours of gameplay.)
If I were to put Civ V away now due to its various undebatable shortcomings, it would be a much worse deal than Civ IV+BtS eventually turned out to be, but still compare favourably to most other games I buy. I do however expect the rough edges to be smoothed out over time, I can wait if that means I'm getting a better deal after all.
