That's right, a Game Boy.
Not Game Boy Advanced, Color, Light, or anything fancy like a that, but a slab of solid grey plastic straight from 1989. My girlfriend got it from her grandmother, and gave it to me as a birthday gift. The only games she still had to give me were Pokemon Red, and some combi-cart with Tetris and some tank game. They're fun and everything, but some variety would be nice.
Therefore I'm asking you guys, what games on the old classic Game Boy due you recommend to me? I'm thinking of getting Kirby's Dream Land, but other than that my hand held knowledge is slim.
