[This is only about Zork I] I'm honestly surprised by how much fun I had, especially considering I kinda expected myself to get bored/frustrated quickly and end up following a walkthrough step by step. The key part was using all the docs I've got with the Classic Text Adventure Masterpieces collection, so the maps, the lovely hint book and the manual with the background story. Those things gave me a big hand in terms of quality of life and helped me immersing in the world and the whole spirit of the adventure. Plus, they are so much fun to read, clearly written with Terry Pratchett and Douglas Adams in mind. The game is of course rough, primordial, it's quite far from being one of the best text adventures out there, but with this approach it was really fun, entertaining, and I was able to appreciate a lot of complexities I didn't expect to find (the whole thief part, how it tackles fighting and dying, some lovely puzzles and the bizarre, funny writing). I'm not sure I would encourage anybody to play this game instead of other later Infocom adventures, but I would for sure encourage to read and use all those docs anybody who wanted to play Zork.
