If I were you, I wouldn't trade iut for the world. I have also completed my RSdex, and I see it as one of the biggest accoplishment of my pokemon loving life. It takes a lot of hard work and dedication to achieve this level, and shouldn't be parted with easily. Fifty bucks is the same as any other fifty bucks, but your R/S game is like what you really are. it has your favorites , your deeds recorded down into the Television shows, Your saved Secret bases, your Fans at the trainer house, all your shinies, all your hard work, your league hall of fame. To just part with it now that it is completed is like selling a portion of your soul. You can take satisfaction from your hard work and noone should be able to put a price on that. Knowing you did it all by yourself and with no help, being able to look backon it whenever you choose, should be more satisfying than any amount of money anyone can give you. (End sermon:) )
