When I was young and living paycheck to paycheck I did pirate some PC games which I would never have been able to play otherwise. Whenever possible I bought them when they dropped sufficiently in price.
I have modded my Wii, after five years and only grudgingly when it appeared there was zero chance of getting Xenoblade, et al in NA. I imported Xeno, TLS, Pandora's Tower, FFII:CB but 'pirated' others like Disaster:DoC and FFIV which I couldn't import. However, I'm a collector and have boosted my Wii collection with games I will most likely, never actually play but enjoy just seeing in my collection. Whenever I do end up playing one (for more than a few minutes) I do try to purchase it (Ivy the Kiwi? for example) although often their simply not possible to find anymore. I have 50 Wii games I bought, and another 50 I've bought and since sold (but still have digitally), 3-4 of which I rebought because I began playing them again. And another 100 I've pirated but don't play and won't likely ever play, and therefore would never pay for them, despite being 'good' games.
