This game is even more intoxicating than it was on the N64 for a few reasons: -
The developed graphics give it more life and look stunning in 3D, however, I recommend you avoid if you suffer with photo sensitive epilepsy, there is a lot of flashing lights.
It allows you to select a control pad mode (either N64 or 3DS) I found the 3ds "moving" controls quite hard to master, so I stick to the N64 controls (you still get 3d view either way)So it caters to different people in terms of the fact that some people might find 3ds control style too hard.
The battle mode gives the game even more than the original, can provide hours of fun for your kids.
The gameplay is in enhanced and smoother, again, giving the games more character.
