Pathfinder: Kingmaker is an RPG with very old-school sensibilities. That has its advantages - character customisation is very deep, and there's a wide variety of different builds you can come up with. Skill choice, alignment and roleplaying actually matter, and there's a lot of very interesting choices to make in the main plot (and some of the sidequests). However, the game is also rather unforgiving. There is very little hand-holding, and nothing to prevent you from painting yourself into a corner. If you go into an encounter unprepared, you'll just lose. I'd say that the game is "tough but fair," but unfortuantely it REALLY goes downhill towards the endgame. Let's just say that you should take the Blind Fight feat for every character if you want any hope of ever completing the final dungeon. And probably keep Death Ward handy. And Mind Blank. And Freedom of Movement. And Delay Poison.
Deadnaut is a failed experiment. It tries something interesting with its aesthetics - its lack of explanation, its information overload - but it just isn't fun. Imagine you're playing a Roguelike. No, scratch that. You're not playing the game yourself. Instead, you are controlling someone who is playing a game - watching them through a grainy surveillance camera, listening through a crappy microphone, and trying to give them instructions on how to beat the game. Is something exciting happening on screen? Maybe. Are the mechanics fun? Quite possibly. Is there an athmosphere of dread? We can infer so. But we don't get to experience any of that, because we don't get to play the game ourselves.
