If I download a pirated game it’s because I don’t intend to pay for it. It’s a choice between pirating and not playing it at all. Sometimes I like the game so much that I do end up buying a legit copy too, but that wouldn’t have happened if I didn’t get to play it first.
For Switch in particular it’s because I’m a PC gamer and can’t get used to playing games on console. I do own a Switch, but I find it inconvenient to use vs the PC. I played a lot more on the emulator than I did on the real thing.
I was looking for one of my favorite games from 1993. Not only is the developers website still up and you can still download the demo version and soundtrack from them, but I found some random guy rewrote the whole game in Javascript with WebGL and it can be played in a browser.
