If there's no way to get the game, I don't have an issue with someone getting the game even by illegal means. If you own a copy of the game in some format, I also don't see an issue of getting a copy of it to play on another device(digital copies of PSX or PSP games so long as you own a physical copy.)
If the game is current and being sold still, then it's affecting the company by pirating it. I'm against that.
With what the OP is asking, I'm okay with it, but say how Games For Windows Live is shutting down and it's a game that's available for purchase elsewhere. Even though you can't purchase it on PC, doesn't mean you can't purchase it on consoles. If you're going to pirate it for PC, atleast purchase a console version of the game so developers profit something since the game is still technically available.
