I don't know how I feel about piracy in itself.
First, obvious arguments that you probably saw everywhere in these 10 pages, for people who can't afford games, piracy is actually good. They would never buy the games anyway, but thanks to piracy, at least they buy the console so they contribute to the video game industry... Too bad this is balanced by people who could afford games but pirate them instead.
Onto more personal stuff that maybe only applies to me, it is great to be able to install pirated versions of games on the 3DS after buying a cartridge for example (because a cartridge is a better possession than a digital download (which will be useless once the eShop closes) but annoying to use)... But actually it's almost too easy now. I mean, I went out to buy MH4U last year, and that kind of motivated me to play it. Then, when I wanted to play it more, I looked into getting it in cia form for convenience (it was a time when you either had to convert or find it, but finding it was annoying, like getting on that iso site, logging in, finding only USA versions when you're from EU, etc, so I really only did that when I was sure I wanted that cart into a cia format). But now, pirating is so easy on the 3DS that just about any game can be downloaded in minutes, so I'm no longer motivated to go out and buy, but if I don't get out and buy I am not motivated in trying games as hard either... So I just almost never buy anything but I don't play pirated games either. It's almost like piracy killed my motivation to play.
Now please, read the beginning of the previous paragraph again please, "maybe only applies to me", I do not blame anyone here, I'm just weird. Also, this only applies to games. Because most games are boring at first and better after that, so you really have to force yourself to play to actually start enjoying them. But for movies for example, it's another story. It's only like 2 hours so you don't force yourself at all. That's why here ok, I got a pirated Frozen download (can't see it in theaters after 2 years so I'll only see it on a small screen anyway), watched it, liked it and bought an Elsa plushie to show support, for twice the price of a DVD (which by the way would have been annoying to play since I don't have any DVD player) and three times the price of a cinema ticket because I don't care, it was good.
