See, that's interesting - back when I copied games, even when I liked them, the thought never occured to me that I should buy them afterwards, mostly because I just didn't have the money. I now feel really guilty and am considering buying a shitload of back-catalogue to make up for my sins
I actually did this after I got my first job.
I went and bought every single game I ever finished as a pirate - more than 80 games!
And now I own around 400 games, steam sales make it so easy...sigh
