Rumours are rife that a new Nintendo DS with motion controls will be coming out to help hold its ground against relatively new contenders such as Apple's iPhone and Sony's PSPgo. In imagining the new possibilities such a console may bring (all the interactivity of Wii with the mobility of a handheld?), I decided to check out some creative titles that DS game developers have already brought to the table. I grew up with the GameBoy and its successors, and the onslaught of games which accompanied my childhood started blurring together after Mario.  But every once in a while, I would come across a memorable one. A game that defies convention, whether it's in a big or small way, and brings a breath of fresh air to the congested and competitive arena. Let us introduce you to five such titles on the Nintendo DS. Disagree with our list? Chime in with your comments on the games you think should be included! Here they are, in no particular order: 1. Scribblenauts When I became hooked on this game's extremely simple concept, I asked myself: Why didn't someone think of this earlier? The objective sounds deceptively easy. Depending on the mode you're in, you either need to devise a method to get your hands on the star in every level, or achieve whatever the game tells you to do - like 'give the cook three things to eat', for example. But here is where the genius part comes in - instead of just putting enemies and obstacles in your way and making you fight your way through, you conjure up items to help you clear the level. Enter whatever word comes to your mind, and the object (or a representation of the concept) will appear in the game, ready for use. Anything? Well, pretty much anything that's in the game's impressive dictionary of over 20,000 words. The game even recognises 'merlion'! A pity the developers aren't more familiar with our culture, though. It would have been nice to be able to cook up a bowl of bak chor mee in the game, or pit an 'ah beng' against a troll. 2. Electroplankton It's difficult to imagine the gameplay of Electroplankton, so I've embedded a video for some audio-visual help. Did you think the idea of Scribblenauts was weird? Well, at least it had an objective. Some may boot Electroplankton out of the games category because this music creation title does not set any aim for you to accomplish. However, it can still be a really entertaining time-killer. You choose from 10 types of plankton - each one makes a different sound and can play varying roles in your masterpiece. After you've chosen and arranged them in your nice sequence, you can listen to the wondrous music that you've just composed - and watch the entrancing visual effects that accompany it. 3. Treasure World DS This unique title allows you to 'see' your surroundings in a totally different way - through wireless signals. It senses WiFi signals around your present location and employs them in your gameplay. Just imagine that each detected WiFi signal is a treasure chest, and you have to go to many locations, hunting for different hotspots to get new loot. Each treasure chest, in turn, will contain a different collectible item, like a t-shirt, that you can either sell to repair your ship, or use to decorate your avatar or game world. Fortunately, our technologically advanced sunny island is chock-full of them, and Treasure World DS will turn each of these signals into a collectible item that will be automatically added to your virtual inventory. Lack of storyline aside, this is a fun and casual game to spend a few minutes with every time you're in a different area. Treasure World DS will make you realise that there really is treasure afoot - you just have to know where to look. 4. Soul Bubbles Ever played a game that completely revolves around blowing bubbles? In Soul Bubbles, your job is to transport a bunch of adorable spirits by ensconcing them in these transparent spheres. Next, you have to make sure the fragile little things get to their destination safely by blowing them towards the right direction, and using them to interact with other items in the stage.  The result is a game that is not only beautiful to look at, but also destresses you. 5. The World Ends With You Before I begin extolling the merits of this game, you have to first see it to envision what I am going to say: Here's an RPG which actually requires you to dress your character up in the latest Japanese fashion trends. If you don't want to lose any of the fights that this title revolves around, that is. In the game, you are a fancy-pants Japanese boy with a fashion-forward girl partner. I will not attempt to explain the complicated storyline, but basically you have to defeat lots of creatures and bosses by working with your sidekick to execute cool moves. One of the ways to sharpen your combat skills is to buy and wear clothes from the various boutiques in the game. How's that for dressing to impress? One other way in which The World Ends With You departs from the norm is how you control your characters in combat. The tricky part is, you have to control your character with the touchscreen, and his girl pal with the buttons - simultaneously. Plus, the buttons have to be hit in a certain sequence for her to deal maximum damage and join forces for a smokin' cool combo. Sounds like a design flaw that will frustrate players to no end? That's what I thought, until I got the hang of it and became addicted to the game. <object width="480" height="295"><param name="movie" value="http://www.youtube.com/v/gLlURPGVDsg&hl=en_US&fs=1&color1=0x5d1719&color2=0xcd311b"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/gLlURPGVDsg&hl=en_US&fs=1&color1=0x5d1719&color2=0xcd311b" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="295"></embed></object>
