Best Gameboy or Gameboy Color games?

Not always a ton of love for the Gameboy, it seems. While the games were quite a bit limited, Nintendo did squeeze quite a lot of quality out of that system. What were your favorites?

I liked:

Link’s Awakening - Amazing Zelda game and surprisingly deep for such a small storage space.

Warioland 2 and 3 - Both of these are under-rated gems. I love Wario 3 especially and it is one of the biggest GB games out there. Took my wife and I forever to collect all the keys and treasure.

Oracle of Ages/Oracle of Seasons - Perhaps the crowning achievement for the Gameboy. Two amazing and intertwined games and both are full, great Zelda games.

What are some of your favorite GB games?

There is only one answer: Tetris

Pokémon Red and Blue
Rampage World Tour
Pokémon Trading Card Game (no, really)
Harvest Moon 2
Mario Golf

Battleship!

Can’t go wrong with the Kirby series.

All the Pokemon and Zelda games were awesome.
I played a lighthearted little game a while back called God Medicine that was quite fun.
Trip World is a game not really known for its gameplay but has a bit of a following among pixel artists for its graphics.
