I did pirate software on the Amiga, yes. Mostly because my folks were stingy and I never had much of an allowance scheme. But that's a bad excuse, I know. So if the main cause of the downfall of the Amiga was piracy, of course I regret what I did.
But when you're broke all the time and the games were at your friends next door, it was hard to resist. * Silentbob goes and stabs himself in the head for his stupidity *
Today I try to buy as many games (the ones I like mind you) as possible though. Too little too late maybe, but still.
