Ghosts & Goblins on the C64 in the 80's (I did complete it, but not the cluster **** of go back and do it again as it was all a dream). 
Elite 2 Frontier in the 90's and EVE-online in the early 2000's.
I used to play games to completion and never touch them again its changed a lot now with online and GTA etc.
