The first Flash Element Tower Defense was a kind of revolution. It single- handedly brought tower defense games out of the realm of Warcraft mods and into the world of free online gaming, kick-starting a new genre practically overnight. If you're interested, Dave Scott has published a blog entry about the technical issues and history of his seminal creation.
But Flash Element TD1 wore its influence on its sleeve, with sights and sounds ripped directly from Warcraft III. Now that Dave has teamed with Paul Preece to create Novel Concepts, he has built Flash Element Tower Defense 2 according to the Casual Collective aesthetic ? the audio/visual style pioneered by Desktop Tower Defense and perpetuated by Buggle.
