I remember playing Ultima VI: The False Prophet for about five minutes on a friend's 386 back in 1990. I've been the biggest Ultima fan I know since 1987, and Ultima VI was like Ambrosia to me. It wasn't until 6 years later than I finally got my hands on it. In the meantime I kept desperately hoping either:
1. It would be released on Apple II (hah!)
2. The SNES version would come to Australia, and would actually be any good (also sort of 'hah!').
Neither came to pass.
Other loooong and agonising waits were for:
Faxanadu - I hired this once while visiting my grandparents, then dreamed about it for a couple of years. I managed, as a 13 or 14 year old, to save up almost enough money to buy it - then found myself $10 short and blew the lot on Shadowgate instead! It just wasn't the same...
Ultima VII: The Black Gate - sort of a similar story to Ultima VI, except that I only had 4 years of crying myself to sleep this time round.
Super Mario Bros - first played in 1989, didn't own until Christmas 1991. That was a HAPPY day.
What are other people's stories of delayed requitement?
