I love all the nay sayers about TZ. It's a great game with lots of different objectives and different modes. TAF is easy, fun, and has great modes as well. FH is hilarious, the easiest of the bunch, and is rising in value daily as people realize how much fun it really is. I've never played TSPP so I won't say anything about it.
But, production numbers don't lie:
TAF - 20,270
TZ - 15,235
FH - 10,750
TSPP - 4,400
I'd have to say that this order holds true for their popularity to this day. To quote earlier posts: "There's a reason for this." You tell me which ones did well on location and which ones didn't. B/W isn't going to make 10,000 of a game that performs poorly on location and isn't fun to play for a lot of people.
