Moto Roader immediately reminded me of Legend of Dekoboko, another "car combat" game that insists on having all five racers onscreen at all times and smacks the bottom feeders forward when they fall too far behind. The memories of Dekoboko caused me much stress and vexation, as I did not enjoy that game. But I soon discovered that MR is a far cry from the debacle that is LoD.
Instead of walloping you with the edge of the screen and causing spin-out chains like Dekoboko does when you're trailing, MR simply gives you an oftentimes helpful little nudge that can be implemented tactically if you're willing to take some chances. And MR knows what it is; it knows what makes itself tick. Dekoboko is a failed attempt at cuteness: it tries so hard to incorporate "wacky" elements that it ends up being a slow, annoying obstacle-course run. MR, on the other hand, concentrates on providing simple, fast-paced fun.
