I'm happier with the rewards this year than last, but that's just a function of me owning fewer of the games being offered. Overall, I'm pretty happy getting Tropical Freeze for free. Prices for that game never dropped far enough to convince me to buy... but it's probably something I'll enjoy.
To anyone who already owns all the games they want from what's listed, sincere condolences. We all kind of knew it would work this way, but that doesn't make it any less disappointing for you. On the upside, you can probably sell or trade your prize with a fairly low amount of effort.
And to people who waited until the final hours to try and enter codes and then didn't make the cut, derisive laughter. Seriously: you knew the deadline long in advance, but trusted Nintendo to keep servers alive and responsive until the last minute? Anyone who frequents the forums here should be smart enough to know better.
