By the time you win you would've paid more for cards than it is worth it trying to get the scholarships. You also have to remember that your going to be moving up in divisions (if your not already a master) and such. Kind of like winning the lottery. You play it so much that by the time you win even 100 dollars your just getting your money back.
Ah, but then we have the VGC... Alas, though; I digress.
As these past few months have rolled on, the value of playing this "children's card/video game" has grown. As a young teen, an ideal thing to have - at least for me - is some sort of social group that gets you, albeit any minute differences etc. you may have with person to person. Since in school I typically have troubles finding a group that "clicks," Pokemon has provided that instead (though not to say I haven't had any in school; on the contrary, I have, they just don't last long for one reason or another). Besides, there's that serene and otherwise unique feeling you get as you step into the doors of a tournament. At least for I, after a second of walking into the door, a good portion of the people there know my name and face, Hmm... Another family, if you will. Hardly anything outclasses thrills a tourney has in store, even on a Sunday when you know very well school comes the next day.
