OK so I've played this for a few hours.
It looks OK, it's so dark I can't really make out any real detail but whatever.
Combat is uneventful basically hit, dodge, hit, dodge. I appreciate it's about timing but that's what you do.
AI is OK, they get pulled into choke points fairly easily but in open areas they do surround and attack well.
What I've found most frustrating is the lack of progression, I appreciate the gates are meant to be the "check points" which is all well and good but when you die and lose everything it gives you no desire to come back and get it. Same issue with DayZ after you've died and lost all your stuff it just grates having to go back and get it. I'd go back to the shop guy in the well and buy stuff but the 2 minute loading screens are awful and further reduce any real desire to press on.
It also has hilariously bad voice acting.
I imagine a lot of my issues with the game could be resolved by sorting the loading times, would allow me to drop back, have a small break and head back out stronger but in trying to avoid them it's making me push forward into things I'm not prepared for.
Oh and using all your Molotov's to progress, dying afterwards, not getting the Molotov's back but the enemies return is just silly, that's one of the biggest criticisms of Far Cry 2 where the enemy camps just refill every 5 minutes but here it's a good thing? Double standards.
The high difficulty thing it's so heavily praised for isn't what I'd call difficult it's more like a don't mess up situation rather than it being particularly hard. Not getting any sense of dread when I'm approaching things like I did in Metro 2033 Redux on Ranger Hardcore mode, nor do I feel any accomplishment when I do get past a large group or whatever.
Quite disappointed so far, I'll keep going to see if it improves though.
