okay then, let me start off by saying you have lack of gameing knowlege and/or gba experience.  so,  i would defidently reccomend metroid fusion.  you said rpg's weren't your cup of tea, so A Link to the Past is great.  some great pick up and play games are Mario Kart and Super Monkey ball jr.  kirby is short but sweet, a good pick up and play.  but difedently super mario world, if you don't have it for the SNES.  but you should really give rpg's a try.  golden sun 1+2 are great, as well as pokemon.  oh well...
