I actually had a chance of getting it early, but turned it down.
My town's first ever Game Stop opened this week, and they've got this insane opening offer where you can trade 3 last gen games for any 1 new game up to 75€ in value. After checking the place out I went to the old independent store across the street to buy a used copy of Alien Hominid for a geeky party we're having on the weekend, because the new store didn't carry it. There I made after-purchase chitchat with the clerk, and he asked if I wanted to buy Super Paper Mario. I was rather surprised, but of course wanted to get it for practically free at the other store, and turned him down saying I had just expended my gaming budget for the time being. I forgot the game's release date was on friday, so I went to the Game Stop and asked them if they had the game already as well, and managed to blurb out that the guy in the other store had offered to sell it to me. Turns out they didn't have it yet, but they were happy to take note and report the other store to the local Nintendo representative for breaking the release date.
A bummer really. I was looking forward to buying Brawl from them as early as possible when it arrives, but they'll probably be more careful with this stuff now. -_-
