Still, I am willing to hear your suggestions and recommendations. Maybe I can just focus in on a few key titles for now.
What say you?!
I'm also interested on hearing your thoughts on Pokemon, (Red, Blue, Yellow, the version dosen't matter.)
I should note that old Game Boy games have limited color on the Game boy Advance/Game Boy Color, so you won't be playing completely monochromatic games. A few games, the ones in black cartridges, play in full-color.
Castlevania II: Belmont's Revenge - The music is awesome and in my eyes, this might be the best of the Black and White Game Boy.
Contra: Alien Wars
Donkey Kong - Another must play. Takes the old Donkey Kong Formula to another level. Plenty of stages to play.
Donkey Kong Land - Basically the Donkey Kong Country of the Game Boy.
Donkey Kong Land II
Donkey Kong Land III
Gargoyle's Quest - A spin off on Ghosts 'n Goblins where you control Red Arremor. Similar to Demon's Crest for SNES except this came before it.
Gradius: Interstellar Assault
Kid Dracula - Parody of the Castlevania series where you control Dracula as a kid. It is a platformer but it is pricey.
Kid Icarus: Of Myths and Monsters
Mega Man I-V - Basically portable versions of the Mega Man games for NES. Can get pricey though.
Metroid II - Sequel to the NES Metroid.
Ninja Gaiden Shadow - Was originally supposed to be a sequel to Shadow of the Ninja for NES but turned into a Ninja Gaiden game.
Operation C - Another Contra game for the Game Boy.
Super Mario Land
Super Mario Land 2
The Legend of Zelda: Link's Awakening - There is actually a Game Boy Color version of this game called Link's Awakening DX.
You probably collect cartridge games complete so it might be a challenge to hunt down some of these games with box and manual. I just collect cartridge only though so I've been able to get games cheaper. It is much easier to find GBA games complete and sometimes on amazon you can buy some games new for a reasonable price. I also play my Game Boy games on the Game Boy Player for GameCube which makes visibility better but you can also play Game Boy games on the Game Boy Advance or GBA SP which the SP has a backlight.
I started collecting (after a 15 year hiatus) in 2007, when Gameboy games were still being sold at GameStop. This allowed me to amass a decent-sized collection of these old games relatively cheaply.
This is exciting news. I play my Gameboy and Gameboy Colors on my GBA SP-101 with nice backlit screen. Boosts the color palette for the original grey Gameboy games (at least its a whole bit better than 4 shades of green). I also play them on the Gamecube using the GBA adapter and disc, and use those controllers. I have not used the SNES adapter, but I don't recall any negatives with the Gamecube adapter.
I will also advocated Links Awakening and Star Trek 25th Anniversary. Tetris is interesting as the systems killer app that moved product - and how different is it really from my logic based games through the years - Freecell, Shanghai, to Angry Birds today. If the world of portable gaming began with Tetris, and mobile gaming with Angry Birds, then how different are they.
As for adding to your collection, since Nintendo original Gameboy compatible handhelds like my SP are fading fast in this dual screen world, maybe GB and GBC prices will fall or their availability rise sharply in the next year or so. Spring is garage sale time, so maybe its hunting season. A good number of all my GB, GBC and even GBA came from family whose children outgrew them and knew I would enjoy them.
