Lets assume that later down the road Nintendo decides to make a SNES mini console with the same treatment as the NES mini. What would be your ideal 30 games?

Oh please let it happen!

Off the top of my head...

Super Mario World
F-Zero
Super Street Fighter II
Super Metroid
A Link to the Past
Donkey Kong Country
Donkey Kong Country 2
Donkey Kong Country 3
Final Fantasy II
Final Fantasy III
Super Mario Kart
Super Castlevania IV
Earthbound
Secret of Mana
Contra III: The Alien Wars
TMNT IV
Yoshi's Island
Chrono Trigger
Mega Man X
Super Mario RPG

Edit:

Super Star Wars: The Empire Strikes Back

SimCity (especially as Nintendo pulled it from VC)

Blackthorne

Goof Troop

Star Fox

Mortal Kombat II

Pilotwings 

NHL '94

Super Punch-Out!!

Terranigma

Oh and bring Terranigma to North America already!

Appart from the well known Nintendo classics like ALTTP, Mario World, Yoshi's Island, Super Metroid etc and a bunch of multiplayer games it would be cool if they included things like Demon Crest, Final fantasy VI, Chronno Trigger, Earthbound and Super Mario RPG. But most of those games were only translated into english so people from a lot of countries would find hard to get into them, so maybe is not very wise to put many rpgs together.
