For some people especially die hard fans of the Team Fortress games, seeing this map running pretty well within the browser would not mean much because they know that there is much more to the game than a map.
However, for the rest of us, this is an interesting development, especially as it is still very popular with gamers! So what does this mean? First up this demo merely shows that the map can run within a browser, but to play the actual game the player would need some serious hardware, such as a 3D card or APU.
What this does is offer another platform for the game, which can only be good for players and developers, but not die hard Steam fans, check out the developer Brandon Jones own website for more details.
