I believe in piracy for "demo" purposes. If the studio "forgot" to provide an official demo, you as a consumer should take matters into your own hands and provide the 'demo'. Delete it when you've played a 'demo's worth', which did have a fairly industry standard meaning back in the day.

When I became willing to play this 1 older game that shall remain nameless, and pay for it, I went looking for a Game Of The Year edition to pay for or some such. For some reason, this particular game never released a comprehensive GOTY. They expected you to download a quite silly amount of expensive DLC for trivial features. Slightly more powerful items in a RPG, basically. Those items even had the effect of ruining the game balance, so I'm not convinced it was even a good idea to have the DLC. Yet they expected you to pay for it sight unseen.

This was all driven by some kind of big corporate trick or scumbagging. I think it was an EA published title. Because they were clearly being greedy with an older title, I said to hell with them. It is one of the only games I've played in its entirety, that I didn't pay for, that wasn't abandonware. If you're gonna be like that and your price on goods is not reasonable, I don't feel I have to cooperate with you.

Now that I know what's going on with DLC games, and also the low level of quality that's going to result when a publisher engages in such practices, I'm not likely to seek a 'demo' of such a game at all. I will probably retain my demo only, not pirating purity in that regard. But to the extent I've ever been impure, that once, it was directly driven by the DLC. I was like waaaat, srs, gtfo.
