ActionTrip has reviewed Myth III and was a bit harsh on it, giving it a 71% overall score. Other than the strong story and visual content, ActionTrip couldn't get over the flaws and lack of innovation:
Mumbo Jumbo obviously could've done a lot better. Not only did they slack off while writing AI routines, and ship a buggy game, but they also didn't innovate the series in any way; let alone take it to the next level. As a big fan of the Myth series, I find it inadmissible that someone could sit on such a wealth of potential and do such a sloppy job in the end. Myth III was still fun to play, though at times extremely frustrating, but it pains me to think what Bungie would've done with it, had they the chance to do it themselves.
The user comments reveal to ActionTrip the short development time Mumbo Jumbo had, but they still stand by their review.
There is also an image gallery; enjoy. (Thanks Myth Village)
