Put, maybe, 4-5 hours into it now - got the first batch of bike upgrades done, but only a couple of areas on the map covered.
It hasn't blown me away if I'm honest - and I love post-apocalyptic games/films, so it is right up my alley. It's hard to put a finger on it really - it feels [to me] to be a slightly more polished State of Decay from the Xbox; though the bike adds a slightly different dimension to things.
Graphically, it looks alright to me - some textures have really impressed me - the dirt floor of a north west settlement for example, whereas there are plenty of signs and posters knocking around, that aren't even legible, due to impossibly low textures. I'm still pratting around with TV settings for HDR, so can't comment on how that looks.
Some things that have annoyed me though:
The game frequently changes your weapon - so if you're trying to be sneaky with the crossbow, then decide to throw a rock - the game will happily equip a bloody gun after the rock is thrown; forcing you to have to pick the crossbow again! This has caught me out a few times now, and you really have to pay attention to that bug/feature, or you'll end up blowing your stealthy approach.
The AI is pants, utter pants - and they fall foul of one of my pet peeves too - they are psychic!!! You can be in the dark, hiding in a bush, and take out one of their buddies - only to get near pin-point shots raining down on you from their mates. The 'freakers' aren't as bad - but interactions between them and enemies can often be comical - using rocks to draw them in, they can almost be standing next to an armed guard before either notices each other
It's just not as polished as you'd expect from a Sony flagship title to me, which is quite a shame - I can see me persisting, but it's likely to be a game that I play in dribs and drabs; as it'll bet repetitive and dull pretty fast.
