the biggest problem against unity

there are some features that they are not that hard to implement but unity guys don't add them to the engine. did you think before about it? why they don't add soft body physics? why should not they add a HTML browser inside unity GUI? there is a big problem that they should think about it. i am not sure if it's a problem in their vision or not. i am not much experienced to be sure about what i say. the web player size is something important. unity's web player is not as popular as it needs to be so the size should be as small as possible. adding all physx features will add about 12 MB to the player size. there are two approaches available. they can add some features as web player add ons. this will add the problem of game size. the games will become so big. the second approach is to rely on users. you should tell them to install physx and install x and y and ... what is the best approach? maybe none of them. should they add features one by one? should we wait for the web player to penetrate more? there is another problem too. some new versions of third party libraries that unity uses are available but they are not backward compatible and adding them will break the compatibility of older games with new web player. this is not something good even for big giants like flash that most users of computers have. I would be more than happy if someone from UT put a comment on this blog post. i might email it to them.
