Surprised Postal didn't make it onto those lists. Then again, I quite enjoyed parts of it! (I can';t even describe it on a tasteful forum!)
My dad had Custers Revenge - it was rather bad :D Plenty of rubbish games I remember on the Speccy though.
Clearly nobody has ever played Cheetah Men or its equally abysmal sequel ;D
Enter 'Big Rigs'. The courtroom was in tears. Of laughter.
