stating the obvious

Whoever has the license to Mahoujin Guru Guru really should make a DS game out of it.

If you're not familiar with it, the entire anime series is a super-kawaii parody of old console RPGs. But crucially, the magician girl character casts her spells by drawing patterns in the dirt with the end of her staff.

So, while there were some SNES games for it, none of them could work in the really obvious connection like a DS game could.
