Call of Cthulhu is an example of a game that could have been but is tragically brought down by extremely basic gameplay elements and a total disregard for story characters. Minor bugs aside, I can't see many enjoying this game, but perhaps, just like anything negative, it'll become a cult classic two years down the line.
Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy takes the saying 'Truth is stranger than fiction' to a level that not even children can believe. If you can look past the ridiculousness of the contrived drama you'll find plenty of gems in the form of delightful brain teasers.
Matterfall ticks most of the boxes when it comes to a side-scrolling sci-fi game. Great visuals, great sounds, robot enemies and lots of jumping and shooting. It's rather short and doesn't have much replay value, but it you enjoy a good sci-fi game, then you should give this a go.
Whether you're looking for 5 minutes of brain bending challenges or just some academic fun, Dr Kawashima's Devilish Brain Training may be the game for you. It does take a long time to unlock all the content, but when you do, you're spoiled for choice.
Kirby's Blowout Blast is a quick and simple game for any gamer no matter what you platformer skills are like. While you can finish it in one sitting, there are worse things you can spend the same amount of money on, like movie tickets to see the latest Transformers.
Miitopia is a strange and creative game. It takes the kooky little Mii characters and brings a little extra dimension to them while remaining bizarre and entertaining. The RPG element of the game is lacklustre, but the interpersonal relationships and friendship bonds are what makes you want to keep playing.
