I don't really have a ton to say about them because I am bad at video games. I just despise the mechanic of Permadeath+Randomization. Everything about the genre screams "get good" while punishing all the central premises of learning. It's just random difficulty while feeding you semi-similar levels on the supposed "beginner levels". Every so often you'll have some bullshit happen that wipes all of your progress, with not a single save point in sight.
Look I'm playing games to have fun, not to feel like some super badass that has mastered every possible mechanic a game can throw at you based solely on the beginner levels. It just feels like the genre exists to punish you, rather than to foster enjoyment.
FTL is great, anyone who says otherwise will go to the gulag
