16 hour plane ride...?

so my ds has pretty much sat in my room for the last year and im about to go on a trip which involves a 16 hour plane ride, so i was wondering what games you would recomendded me to get? I own New super mario bros,mario kart, advance wars, the mario basketball game,pokemon(i lost it tho), also my favorite handheld game of all time was final fantasy tactics, anytihn like that out there

id really reccomend pokemon, is there really no chance of you finding it? if so then maybe buying it again?? well i guess you've already played it and would know if you want it. it's just that i know that would be one of the very few games I would play for 16 hours.

if not, then maybe FFIII or Animal Crossing DS.
