I only played a couple of hours of Hacknet but was quite disappointed. Cli is really bad, no pipelines, no command chaining, almost no commands, even the most simple commands like cd and ls are shitty. Your hacking is limited to less than 10 commands and always looks the same. You scan, you exploit with binaries, you collect new binaries (there are a couple of other things such as time limits, limited RAM etc. that make it a little bit more interesting but not that much).
Story is ok though and it is quite fun to read chat logs etc., they put some fun stuff in there.
