Star Tropics.

Wave Race, unfortunately dead as a Dodo :(

Damn, I had totally forgotten about Golden Sun. I'm going with that one. Awesome games.

F-Zero, luckily we had FAST Racing Neo/RMX to fill the void, well for me it did at least.

Advance Wars by far, was proably my second favourite Nintendo handheld IP behind Pokemon.

luckily the indies have had me covered with games like Commanders: Attack of the Genos, Skulls of the Shogun and the upcoming Wargroove,Tiny Metal.

Advance Wars. I love me some modern Fire Emblem, but through the DS era that was my favorite strategy series period.

Yeah, as an F-Zero fan myself, Fast Racing Neo temporarily took away the pain. :(

Star Tropics would be my pick.

And even if I havnt played Golden Sun, it looks like a great series and I kind of want it to happen again ^^

Mario Party (It's dead to me.)

F-Zero
