Advance Wars.
That wasn't one game, but an entire series that compelled me to buy a GBA (two, in case I lost or broke one) and then a DSl for Dual Strike and Days of Ruin.
None of those were on any console.
Also Brain Age. It was conceived as a DS game series that sold a ton of handhelds to the extended audience.
