hello, I was wondering if there were an .exe unitywebplayer where you could just drag and drop .unitywebfiles to play them, just like all those external flash players such as this one http://www.globfx.com/products/swfplayer/
And if there isn’t one, how to make one? 
You can either have a web-player build or a stand-alone build; as far as I know there is no such thing as a ‘stand-alone web-player’ build. Why not just use a regular stand-alone build?
correct, no such thing as standalone webplayer as you don’t need it (if you want to be that harsh you can provide the webplayer + html and force them to open the html or have a fake application that does nothing but open it … but thats a waste and restricts your possibilities), a standalone is significantly more powerfull and native 
What is the performance increase of standalone compared to webplayer? I am assuming a lot, I was just wondering if there were any comparisions anywhere
