Never played on a 3DS, my friend says it's great though, and even though both my DSi and (classic) DS are broken, I prefer my freezy DSi to my buzzy, hinge-breaky DS.

i like the dsi but im planing to get a 3ds soon. and if its good ill re-vote and vote for the 3ds. but for now ill stick with my dsi.

I absolutely adore my DS..definitely love the original DS and the Lite..but I haven't tried the 3DS or the DSi.
