xordiw: Honestly I did not played it myself :) I read the reviews so I did not buyed it.
Well, if you find a cheap bargain somewhere go for it. If you liked the first 2, you will love it.
I think the reason it was called bad, was because the game-play wasn't innovative enough. Plus at that time, multiplayer was the hype, and Myth 3 wasn't made for it. Its story was excellent though, and its single player experience pretty solid.
GameSpot's Sam Parker scored it 8.4 out of 10, writing "
Myth III's single-player game represents the best the Myth series has to offer." He
praised the 3D graphics and the storyline, lauding the decision to make a prequel. However, he was
critical of the absence of many advertised multiplayer features, the absence of Vengeance, and compatibility issues with Windows XP, expressing concern as to whether MumboJumbo and Take-Two would provide the same level of technical support that Bungie had for the first two games. He concluded "
Myth III isn't as well polished a game as its predecessors, but its strong single-player element and solid graphics make it a remarkable game in its own right."
PC Zone's Keith Pullin scored it 7 out 10. He
praised the gameplay, the importance of tactics during combat and the graphics, but
criticized the repetitiveness of the single-player campaign, concluding "While this third instalment of the series boasts some commendable touches, it rarely manages to fully explode into rip-roaring RTS action. Myth III seems to coast along without ever really breaking sweat."
