Sonic Rush - perhaps best 2D Sonic Yet
This is an excellent Sonic game, the kind that would have been made for the original if technology had been available. It's smooth, responsive and yet provides a challenge. Unlike Sonic Colours, who's difficulty level would patronise the average five year old, it provides a manageable but still challenging series of levels.
As usual the plot-line is not only lacking but actively irritating, leaving you to wonder how much important game information would be lost by skipping all of it (not a lot is the answer). The side missions on water-skis are reasonably entertaining and the random 3D free wanderings help to flesh out the 'Sonic World', but are not entertaining enough to justify their inclusion.
As usual, the game comes down to nothing but simple game play, and in this aspect it succeeds. It's fast-paced but not so much as to force you to memorise the level's layout just to know what's coming. Additions to the basic 'run and jump' abilities are most welcome, and include targeted in-air movement and speed-boosting abilities.
The change of style in the end bosses from the originals of the Master System and Megadrive are also greatly appreciated, as they challenge one's ability to think, and don't always rely on a simple 'hit then avoid being hit' repetition.
