Need a GBA game..

I'm gonna go on a trip really soon, and I wanted to buy a new GBA game so I can play it on the way there. I don't want it to be really short, because the trip is for two weeks or so. So I was wondering what game I should get. I have,

 Mario and Luigi: Superstar Saga

Golden Sun 1 and 2

LoZ: Minish Cap

and a couple of other ones, but these are the kind of games I like. Any one have any recommendations? I heard FFIV was good, and so was Riviera, but I'm not sure. 

well... kinda depending on how long of a trip this is...i would either reccomend final fantasy 6, or final fantasy 1&2 ( those being for a long trip) or, castlevania for a kinda long trip but kinda short like 5 to 6 hours

anywho

good luck

later

Pokemon would keep you occupied. Get like sapphire/ruby/or that emerald one.
