Bungie.org's Lophan wrote to let us know that Freewill has posted an E3 report on Myth III at Myth@Bungie.org. In addition to spotting the Myth III boardgame-- more on that at a later date-- he commented on what's been done so far on Myth III and what is still left to go:
The team readily admits that they have yet to touch a good portion of the original Myth 2 source code: they've spent a big chunk of the last few months getting the graphic engine and other assorted stuff to the point it's at... and boy, does it show! Trees sway, dwarven cocktails light areas and such as they arc through the air: just gorgeous. The wight blast especially was quite beautiful: a shimmering blast of purple particles slamming into units! But other elements like AI, pathfinding, etc. are still very native Myth II. So folks that are claiming that they've witnessed no clumping are basing that on purely empirical evidence and not factual... I'm sure the guys will continue to make tweaks to it to really make it their own.
Be sure the check out the full report.
