well, yeah budget is the key issue. I have a massive list of everything that i wold like to legitimately purchase, but face it, i'm a student, i don't really have much of an income, most of my big splurges are at Winnipeg Ai-kon and C4(Central-Canada Comic-Con)... however i try to do my best to support the producer of the product.
When it comes to games, i wait on the game and research it thoroughly before even making a purchase, that's how i avoid wasting money
Same with most anime that i can purchase, i watch it first and buy it if i enjoy it and would like to see it again.
also, who purchases porn? there's so much stuff that doesn't even need to be pirated.
