I had a lot of cracked games, but do you know how many I actually played? I can't think of a single crack that I sat down and played for any length of time.
There were a TON of really really bad Amiga games that companies were spitting out. I'd pretty much boot em up and check them out, and they would then go back into the box forever. If I found something worth playing, I would go out and purchase it. (and either play the crack or use the crack as a backup)
I knew a ton of people who used cracks as nothing more than a way to preview the games to figure out what was woth buying and what wasn't.
IMO people wasting money on poor software helped the demise of the Amiga. At least now you can get into a beta, download a playable demo, or check online reviews/previews to see if a piece of software is worthy of purchase.
