I'd have to say Advance Wars. Though I HATED dualstrike.

Mario!

I am completely obsessed with the Legend of Zelda series.

the zelda's suck now :/ the old ones were sooooo much better

fire emblem, dragon quest, uncharted

Kingdom Hearts, Tales of

I loved the Banjo Kazooie and Banjo Tooie couple, but since those have essentially died I'd have to vote Zelda, which, just barely, beats out the load of Mario games.
