Concerning Mat Cauthon T's initial impressions post in which he claimed the units moved too slowly, Blambi, who was a tester for Myth III, replied with the following:

this is the exact same feeling I had when I first played, and when I asked about it here was the answer:

In M2, regardless of how fast the unit is actually moving, his sprites keep whirring away at a blinding pace. In Myth 3, each foot has to be placed before the next one comes off the ground, creating a very deliberate feel to each step and turn. Nevertheless, [the] units are moving at exactly the same or slightly tweaked speeds when compared to M2.

Another funny thing is how fast units move... proportionately to the units, Myth maps are very small. To counter this, units move very slowly. Think of ghols, that you visualize as speedsters near-flying across the ground... the MJ team converted their speed from M2's world units to the real world's miles per hour, and that ghol is really only moving at about 8 mph. That's an easy jog for most reasonably fit people. Dwarves are cranking along at some 2mph. M2's units, with their never-slowing-always-fast-sprites, give the appearance of moving quickly without actually moving that quickly.

That's some interesting stuff. It seems like Myth III's approach was more realistic while Myth II's was more accommodating to the engine.

UPDATE: Blambi talked to an employee of Mumbo Jumbo today who told Blambi that units were speed was actually modified a bit more than he thought:

On HL a MJ guy who saw my first post tonight said that unit speeds have actually been tweaked quite a bit to compensate for the slow-down effect, so much that a M3 zerk runs at roughly the same speed as a M2 Trow.

Got something to say? Get it on the discussion.
