The little details don't fucking end, they really don't.
I just got wet and walked - my shoes made a squelchy water sound until I dried out.
Get in a car and (as per all my posts) - drop to FPS view. Drive very slowly in a car park (I did it at the beach) - the wheels make that... grainy? noise - the noise real tires go where you can hear them on thicker asphalt (It might do this on all surfaces but only way to explain the noise)
This game is in-fucking-credible. I can't help but only play FPS view now - it's much much more realistic, it's a totally different (even better) game, seriously - more people should be doing this.
EDIT: go to the beach at night - there's groups of kids on the beach drinking around a fire hanging out - and different groups with different character models, saying different shit.
Oh and waves come in and out at the beach shore - I don't know if there's a tide yet - but waves actually flow - fffffffffffffffffffffffffffffuck
A random mocapped busker down the beach, strumming on his guitar.
Different people have different walking paces - fat people are slow, some skinnys are in a hurry.
MORE:
People playing tennis on their own (just watch them down the beach) - they miss shots, call out to each otehr and there's at least 2, possibly 3 or 4 sampled sounds for the ball hitting as well.
Also it doesn't just go across, they can hit the ball 'up' as well.
If you walk on to a ladder from straight on or partially to the side, there's 2 different animations - he kind of reaches around for it.
