My little BIG hope, maybe, eventually, i mean let’s just dream a bit, let’s say someday, having titles out which already make proper usage of softbodies will help, getting them into Unity too. The marketing then could say: Hey look we can do this too! It’s not something which only weird individuals want, now it’s common, i mean for instance.
But an “all about physics” approach actually leaves you a really wide open field. You have to focus on certain aspects and tweak them till they are fun as otherwise you’ll be lost somewere in this little space between Newton and Einstein (ok not supported by Havok yet :O).
