From GamesReviews:
"While both the Professor Layton and Phoenix Wright franchises focus on solving mysteries, one tackles it on the ground while the other does so in the courtroom. Perhaps this is why both franchises work so well together. Professor Layton and his young assistant Luke carefully do the detective work, completing a variety of puzzles that uncover the clues and truths about the mystery. Phoenix Wright takes the evidence procured by Layton and uses it in the courtroom with his assistant Maya, cross examining witnesses until a verdict can be made. While Layton continues to be what it has always been, the Phoenix Wright franchise sees new styles of gameplay not ever utilized before."
The top 10 rarest 3DS games of all time are probably ones you both did and didn't expect. Especially if you had these games!
I have Fire Emblem Fates LE, the European one. Not sure if it's as valuable as the US version, but it certainly was in high demand.
Its not often I actually have games on the 'most expensive list' but I do own Rhythm Thief and Layton vs. Ace Attorney. I believe both of them are sealed as well.
NWR:
Presenting a new feature we hope you don't have any objections to.
They said it would never happen, and then they said it would never release outside of Japan. When Level 5 and Capcom announced they were teaming up for Professor Layton x Phoenix Wright Ace Attorney, the immediate speculation was it wasn’t going to come west following the disappointing sales of Ace Attorney Investigations and its sequel not even being localized. Also, there is the complication of having Nintendo as the publisher of the western Professor Layton games. Thankfully, the deals were signed and the game released in North America on August 29, 2014.
gamrReview's Brent Galietti: "Your winner, and still champion of the handheld market, the Nintendo 3DS! It's unsurprising that Nintendo's 3DS is leading the competition, because Nintendo has dominated this market hand over fist since the original Game Boy. With the Vita fading into complete obscurity, maybe Nintendo could rest on its laurels and focus on the Wii U and its next console... or it could release a Super Smash Bros. title on a handheld for the first time ever. They, of course, chose the second option. It wasn't alone in the 3DS library this year, but could any of them win in an upset?"
