Justifying piracy by saying that The Witness' price is "too high" is just reprehensible.
First of all, now that I'm ~10 hours into The Witness with a massive amount of stuff left to do, no, it's not "too expensive". It completely justifies its own price.
Maybe it's too expensive for you. That doesn't mean it's not worth its price. Stop pretending like you're so fucking entitled to have every developer personally meet your own budget.
Second of all, it misses the wider point that assholes would pirate the game anyway, regardless of price.
Historically it was "we're pirating because of DRM!!!" Oops. There's a DRM-free version of The Witness.
Then it was "we're pirating because big companies don't care about us!!" Oops. This is a tiny indie team that worked their asses off for 8 years to bring you one of the most brilliant puzzle games ever.
Then it was "we're pirating because the PC version was shit and we want to send a message!!" Oops. Seems like the PC version of The Witness is fine.
Then it was "we're pirating because I have no idea if it'll work on my PC!!!" Oops. Steam offers no-questions-asked refunds for less than two hours of gameplay.
Stop making fucking excuses and start condemning it without qualification. Otherwise you're part of the problem.
