Piracy didn't kill the Amiga (do you really want to go down that line of argument its been down to death).
But since starting to dig through my games (both original and not) and testing what works and what doesn't i have seen what rune has been talking about some originals don't work (disk are ok) where as the crack versions do... also vice versa.
speaking of which i came across Historyline is it any good??? never seen it before.
P.S I have a steam account with alot of games (and so does my son) but I still use "crack" games.... sometimes it nice to play without having the remember to put a DVD in or most cases they get rid of some annoying problems 
P.P.S Not that games these days are all that great getting pretty boring great/realistic graphics are all nice and good but alot of times they forget game play.
try settlers 7 from ubisoft... they have put a drm on the game so you must be online or you cant play at all... and if you lose connection you will be kicked out of the game and lose your gameplay... if you fansy a fame of settlers7 after 10 years you will not beable to play it at all... ubisoft are very nice guys... you go for the cracked version you have no problem at all... the choice is easy...
