i won a sega genesis probably 14 years ago
they had a competition at West Coast Video near me, and to quality for the final you had to do a 60 second run in Sonic (1 or 2, i forget) on the first level, and the highest scores went to the finals. well i qualified by FAR and he told me I had the highest score by very much and would definitely be the last to go at the finals if i chose to. so of course i chose to.
when i went home, i borrowed my brothers friends genesis and proceeded to practice sonic the hedgehog and MASTERED the first level. I could get passed the first level in 28 seconds. and if you passed it in under 30 seconds, you received a HUGE bonus! so i was a PRO at this game and had it in the bag!
well at the finals that weekend, i went and watched as i found out we were going to be playing Bubsy instead of Sonic. All that practice for nothing. but again, i went last. so people started playing and doing just okay, then one guy did really well. then the 2nd to last guy went and he CRUSHED everyone else, by a LOT! so after he went all his friends were cheering and he was all happy. he was cool with the guy at the store and i'm pretty sure he was tipped off as to what game the final would be. HOWEVER, i went on to pwn him and basically do what he did, but do it better and i ended up winning .
well that's my story . i was about 9-10 at the time (i believe, it was right around when MK1 was coming out for genesis).
