Well one of my friends is willing to sell Pokemon Silver and Gold, while my other friend is willing to sell me Zelda Link's Awakening (original black n white one), all $ 20 each. I only have like $ 30. Which should I buy!?

Realistically, those games should cost you $10 each. I would suggest you look online, but Pokémon games are notoriously susceptible to piracy - Me and my brother have ended up with 3 inferior versions of Pokémon - all with shoddy save batteries that last for the best part of 5 minutes.

If you are into Pokémon, I'd suggest you buy that from your friend (just make sure the save batteries are in working order) - it'll give you more hours for your money. Silver has Lugia (Psychic), while Gold has Ho-oh (Fire) - so your choice of which one to get falls on your preference.

Link's Awakening. You'll still have $10, and you can save that for another game. ^^
But, the choice is yours.

Zelda no question, its not even close.

Link's awakaning without a doubt.

I would wait and get Link's Awakining for Game Boy Color.

Zelda.

So so far it's:
Zelda: 5 ; Pokemon: 1
Though who's counting? The decision is yours.

Dammit! My friend can't find his Link's Awakening cart! Apparently he lost it, though how do u lose such an awesome game!? On the brightside, another friend let me borrow Silver for free. And he let me make a new file
