Heh, you’d think that after all this time something like that would be worth some money… :D
As for personally…gah there have been so many. Most of the 16-bit console movie to game conversions were terrible, as were the Army Men games on the PC, Carmageddon 64 was completly mucked up…the list goes on really!
What really shocked me recently however was when I was playing through demos of games I had been really looking forward to when my old PC became unable to play games. Games like BREED, Chrome, Chaser…they all looked fantastic in the previews but I stopped buying PcZone before they were released so never found out how they turned out…how disappointed I was… :?
