In a nutshell, yes, and by luck for the most part then actual skill on my part. What follows below is what I think would be considered a long post, going into details of the events.
There are three GameStops in my area and two of them had a tournament at the same time while one of them started before the other two. The plan was for me and three other guys to go to the different GameStops and win. We first went to the one that opened the earliest and found out about some last minute rules, which included Wiimote + Nunchuk only, (we all had GameCube controllers) which they said something about keeping it "equal", Battlefield, items on medium, and one minute matches. The people working there had very little knowledge of how to work the game. In tournament mode, there was some issues with setting up the names and they decided to do regular brawls.
A little less then 30 people showed up and when it came my turn to play, I first played against a Fox as Ike. I was really worried, since it was my first time playing the game and I was hoping if any of my Melee skills with Marth would somehow work with Ike, who played a lot differently. I was getting used to the controls and the Fox had far more trouble then I did. My slow attacks easily took a stock off the Fox, then he SD'd two times before the minute was up.
Since they were doing regular matches, Ness and Marth ended up showing up and simply having them there, even if you didn't pick them, was too much for the GameStop people, so they end up wasting time deleting the data every time. Since both of them show up after very few matches, this happened quite often.
Anyway, I moved ahead to the 3rd round because some people didn't show up and I had to face a Link. I don't remember how the match when down much, but it came down to a sudden death. I knew Ike would have a lot of trouble against Link during this moment, so I hoped that whatever I did work, and somehow it did. I shielded, grabbed him, then back tossed.
Next match it was suggested that I picked Metaknight and I did. I was against Lucas and I was losing. Since it was a one minute match, I was also suggested to run and I did. I got caught by an ice attack, but that was right when time ran out. So it came down to a sudden death and I dash attacked (yet another suggestion) and won.
The final match was a Metaknight ditto, and once again, I was losing, so I ran, again, and it came down to a sudden death, again. I dash attacked and won, again. The other player had the same idea to do dash attack, but he had trouble getting it to work with the controllers. Basically I only won because of getting lucky and because of the bad rule set. I was hoping to win a copy of the game, but all I got was something that said "Smash Bros - Local Legend of Wreckage" that came in silver and details for the next tournament in a week.
It doesn't end there. Me and the others went to another GameStop and the rules were set up different. Tournament mode, three stocks, items on low, random stages, and Wiimote + Nunchuk controllers. An even number of players showed up, so I don't think there was anyone skipping rounds. I liked that one a lot better then the one I went to before. At least that one was a lot more skilled based since there was no time limit or sudden death to abuse.
Anyway, my first match was against my friend's Fox while I played Mario, on one of the sample custom stages that came with the game, the one that is surrounded by walls with spikes on top. Such a bad match up for me and I only won because he SD'ed at the beginning, because otherwise without being ahead a stock, I would have lost.. Next I was up against a Link on Norfair and I beaten him down pretty good, then I went up against Lucas on Hyrule Temple, who ran away a lot while I was beating him down. The final match came down to one of the guys who came with me, on PicoChat against his Fox, who won by lifting me off the screen in the Landmaster.
By then the GameStop people found out I already won another store tournament, so I wasn't even suppose to have competed, so the guy who beaten me had a match against the Lucas I beaten earlier. Lucas won and the player got the same thing I got, except it was gold while I only had silver. Not sure how that worked out. He even said how he would have done better with a GameCube controller, which I and many others would have too, but he said it in a way that suggested he only lost because of that despite me winning by a stock ahead and him running most of the time.
That's my life story.
