I realised that in going onto the DS some aspects would be cut, for example, the graphics...
As it happens, the graphics are pretty good for the DS, but its not the graphics that are the problem.
The problem is the control...it seems to miss an analog controller and control of the car is somewhat...jerky - despite the graphics seeming smooth enough.
Other differences lessen the experience, for example...powerslides (an aspect of the Burnout games that I've always found easy) are now virtually impossible to pull off. Shame you need them so often...
These control issues take one of the smoothest, slickest, fastest and most enjoyable games to play and take the fun out of it.
Don't recommend it, to be honest.
