I can't argue with the complaints that Alien Isolation framework was too long. The game would have been way better served if they eliminated all these Atari mini puzzles games to make equipment work, and eliminated all the silly locked doors that you culmatively spend hours to figure out how to unlock. That isn't horror, that's monotonous.
The perfect execution of this game in my opinion, truly capturing that Alien experience, would be to make each game playable in 60 minutes. I don't have a modern day game to compare it to, but there was an old Atari 2600 vintage game called "Adventure" where the object was to find the Enchanted Chalice. There were dragons that attacked you. There were three keys that opened three small castles. And each time you played, all the items and the villains were randomized. You didn't know where the threats were and where the items were to win the game each time you played. Now apply that to an Alien game.
60 Minutes. The ship is going to blow. Object is to survive the Alien and escape on a shuttle before the ship blows, and every time you play, all the components you need are randomly placed, even the escape shuttle hatch on the ship. The ship is falling apart. Lights are flickering. Just being against the clock is pulse pounding enough. 5 minutes left. "The ship will automatically destruct in "T-Minus 5 Minutes" you hear over the ships speaker system. You're running around not knowing where the Alien is. Opening and closing doors behind you. Holy shit the Alien is in the corridor you need to go! Now that's the Alien experience I want!
