My problem with the gore effects of most titles is that everything seems scripted.
Do X damage with this or that weapon on spot Y to put texture or model Z over it.
Back in the days when SoF II was still convincing with its unbelievable number of hit zones and aftermaths, honestly not much has changed since then. A lot of things are more plastic, but the core is the same. 80 damage to the arm and the arm falls off. Always in the same place.
I'm skeptical that Dead Island really does as well as the developers like to sell it. Of course, gore is one of the main reasons to buy and one of the standout features, which is why they have to advertise it so heavily, but it strikes me that it's just not as good as advertised.
A lot of it is scripted and turns into animations - like the hit on the knee, the zombie kneels in front of you and is finished.
In a perfect world, this wouldn't be scripted, but "could" happen if you hit the zombie just right and smash its knee with the punch, but the fact that you can apparently trigger this move by pressing a button bugs me again.
It doesn't really look "real" yet, there also seem to be fixed amputation points and no correctly calculated bone fractures and deformations at the points that should break or deform by blunt force trauma, whereupon the rotten flesh and skin starts to tear when you move hastily and after a while the limb falls off.
Don't get me wrong, I like the gore effects and it will certainly be a fun slasher orgy, but we're nowhere near where we could be, and especially shouldn't be, if a developer is already boasting about a groundbreaking gore technology.
I mean, if you look at this 16-year-old video, you wonder why we're not much further along in that regard.
Of course this looks silly and like rubber and would still need a lot of fine tuning, but physical forces lead to corresponding results and therefore the tearing apart a body has a completely different effect here.
