One of the reviews I watched on youtube had a guy saying he had logged 6 hours playing the demo.
His complaints were the missions "Go to X and collect A", and the humans, as Amanda running is enough to make the Alien come get you while other people brazenly walk around, shout at you and fire guns.
I think in the end we will get a 7/10 game here. Yes they poured a lot of love of Alien into this game, but going around collecting key cards is not a story driven game. When in TLOU did you ever have to go and collect something to unlock a door?
I wish they would just ditch those gameplay elements and try to focus on a narrative. However I hold a lot of hope and I know Al and the team are doing their best so lets see how it ends up.
