Hint: there aren't many. San-X no Chara Sagashi Land (San-X Character Searching Land) offers the exact same kind of gameplay as Quickspot, with San-X trappings. San-X, for those of you who don't follow the Adorable Junk scene, is a sub-label of Hello Kitty creators Sanrio whose characters are ... different enough in some inscrutable way to be separate from the main brand.
So, instead of getting to look at two nearly-identical Katamari Damacy images (sigh) and drawing circles around the differences, you'll be scrutinizing Tarepanda the sleepy panda, Kogepan, the anthropomorphic bread who has depression, and others. And for your troubles you get a gallery of mascot images. Of the same characters you were just staring at.
We don't mean to sound down on the game-- we're actually really surprised at what new genres the DS design is encouraging. There may have been 'look at two things at once and spot the differences' games before, but the DS is absolutely perfect for them.
We've included a few precious screens after the break.
