lol nice title. also cool that you're working towards getting your foot in the door for the game industry. good luck and never lose track of your dreams!
anyway, i'd have to suggest metroid fusion as your first title of the metroid series to play. it has an easy to understand storyline, amazing gameplay, and all that. also metroid zero mission is awesome as well, but i'd reccomend fusion first. both of these are for the GBA though, so hopefully you have one of those, if not get one and these two awesome games. if you're looking for old school metroid, definantly super metroid. when you're done with that, do prime 3 as your first in the prime series as it is the best of the three. then try the first one afterwards, then the 2nd. you can end this metroid nirvana by beating the NES metroid (even though zero mission is the same game) just to see what was so cool about samus taking off her power suit and revealing to the world her TRUE gender.
when your finished with all that, give the game boy (original game boy, the big fat one) metroid games a whirl (look em up on wikipedia, i forgot their names). they arn't that great but still good for one looking into the metroid franchise.
anyway, that'll get you started dude. have fun losing your virginity
