I still use Parsec for remote, and I don't have any issue with it, it works great and I like it. However, they also did offer a free SDK (Unity plugin) to integrate remote play into your game natively (just like you can have "Invite to Steam Remote Play" button from Steam SDK), which was exactly what we needed - and Steam Remote was never working without issues for us, in comparison to Parsec which worked amazingly well every time we tried it.

I found numerous mentions of Parsec SDK and how easy it is to integrate, but after Unity bought it, I couldn't find it anywhere. Only mention was that if you need it, you should contact them.

So I did that, mentioning that we are a small team of students working on a offline co-op only 2 player game in our free time, and that since Steam Remote wasn't working for us and I have great experience with Parsec, I asked what we have to do to get access to the SDK/Unity plugin.

Unity's answer? Sure, no problem, they will be happy to give us access, with first step being that we pay them 1 000 000$ for it.

Like, wtf? Did they even read the email? How out of touch you have to be, to casually ask a small student team to pay 1 000 000$?
