You can buy old consoles and hack them or just use Blue-ray or DVD without any connection to internet (that more private than any PC connected to the internet) for gaming. You can just read the paper books for the entertainment.

You can just use cash. It will give you more freedom and privacy than some hardware junk with a lot of backdoors that connected to the internet anyway. Your PC will not give you a freedom in a country with closed border like Ukraine now, but cash can ;)

All of that hardware junk talks about privacy just garbage in real world, where you can be steeled from the street for the fighting in the war ;)

Your friends and loved ones will provide you with better protection of your privacy in a critical situation than any technology ever could
