Netflix's short stint with FMV / chooe-your-own adventure games highlights a perfect case of difficult preservation - all the runtimes are closed source apps, all the data is streamed from a server, and all the logic is held on the server.
In theory (big caveat) with enough time, effort, and determination you could reverse engineer your way around even the worst Denuvo has to throw. For simple streamed content like images and sound you can always analog-hole your way around preserving content.
But for anything where the key thing you want to preserve, like logic, that depends entirely on a server somewhere existing, that's a problem.
This was a good mix to start with - a serious episode and a fun silly one.
The first acts as a really good introduction for Scotty, giving him a chance to build up his character with some insurmountable engineering problems that, with some coaching, he surmounts. The second is a nice way to round off Spock and Chapel's relationship, poking fun at the mess that following the canon has left us in, using Trelane as a stand-in for the fans.
