As far as 3rd person pics, I only ever saw a few ever released. Some of those ones I haven't seen before. As an aside, Isolation also started as 3rd person.
In regards to AR's difficulty, I can understand the dev's saying they thought it was too easy, because if you play it over and over again, you learn where everything is and it is actually very manageable. I probably wouldn't say it becomes "easy" but definitely not as hard as it first seems. And there is actually plenty of ammo upon repeat playthroughs.
Legendary game though. Intimidating and scary AF, but it seems to always lure you back for more. The best atmosphere and lighting style ever in an Alien game.
Also, Civvie is an awesome youtuber. Highly recommended if you like old school shooters and such.
