Back when NDS Sonic games were good... up until Sonic Colours for the N3DS.
Sonic Colours for the NDS is kinda better than Sonic Colours Wii (and Colours Ultimate of course) in term of ending.
In Wii version, the game's ended after fighting Nega Wisps Armored Eggman.
But in NDS version, after defeating Nega Wisps Armored Eggman, Sonic still has to go to full "Super Sonic" mode to fight 'Mother of All Wisps' who went berserk due receiving many negative energies.
NDS version also features other Sonic's friends (Blaze, Rouge, Shadow, Amy, Silver, etc) while in Wii version the game only features Sonic and Tails.
