Been on a gameboy kick lately. Here's what I got:
Pokemon Red
Pokemon Crystal
Cruis'n Exotica
Mega Man Xtreme
LoZ: Oracle of Ages
Super Mario Bros Deluxe
Kirby's Dream Land
Super Mario Land 2
Faceball 2000
Final Fantasy Adventure
Blue GBA SP console boxed
I haven't gotten around to playing them all yet, as I've been harshly addicted to the pokemon lately...but on those that I played, here are my thoughts.
Kirby is fun but very, very short.
Super Mario Land 2 has pleasing graphics, but like the first game, I'm not a huge fan of the controls.
Faceball 2000 has...potential. I'm gonna have to talk my Gameboy-playing friends (of which there are two) into trying out the multiplayer with me, as I could see the arena mode being pretty fun.
I also have a few GBC repros on the way: Magical Chase, Shantae, Metroid II DX and Daikatana. They're the ones you see all the time with "game" on the cartridge where "gameboy" should be. I ordered some custom labels & I'm gonna see if the PCBs will fit inside normal GBC cartridges (except for Metroid II DX, which I plan on sticking into a black GB cartridge like the other "DX" games).
My next GB/GBC purchases will likely be Return of the Ninja, Crystalis, Kirby's Dream Land 2, Oracle of Ages...possibly Cosmo Tank. Any other recommendations?
