If pirating games count then yes.I've pirated quite a few PC games but no console games. I was really close to download Metroid: Other M but choose not to.
That I pirate a game doesn't mean I won't buy it though. If it's any good that is. I pirated Medieval: Total War, liked it and since then I've bought three Total War games including M :TW plus two expansions. Some games I've pirated because the discs I have won't work anymore.
If emulators count as well then...*looks at Wii*...ugh. But 99% of those games aren't sold anymore so I don't feel bad about it. 
The amount of games I've bought used probably gives me the image of a daemon though.
