i totally forgot this game existed

Trailers were cool, but after seeing the gameplay and animations, got turned off, not quite sure what it is but it just looks stiff, and it's weird cause it almost looks like The Phantom Pain which I really liked. I need a demo for this.

Nope, never even heard of it until just now.

Nobody said perfect A.I. Developed A.i. - reacting to situations in a convincingly human way. If you watch the second video, a soldier gets a grenade tossed him. It explodes and he gets up and walks back to his position as if the wind blew him down. He gets shot in the head next ..... and investigates the area 20 feet in front of him. The corridor fight in the TGS gameplay makes storm troopers look like elites. MGS5 has stellar A.I. the best ive seen, Far Cry 5 and AC: Odyssey have pretty good A.I. (degree of vision is pretty low though). This is Tenchu A.I. 

It's been on my radar, but not a priority

I'll probably get it, just not day 1.

It really looks like a front mission game but it's not strategy so I have no idea what it's like
I'm not gonna buy it without trying it first, a demo maybe

Interested.
