See how long this fish sticks around in the charts

If you're a Wii owner looking for a relaxing experience, this week's download is enough to send you into nirvana, with massages and fish-staring ahoy. DSi owners receive some rather more cerebral offerings, with chess, puzzles, music and even a learning game. No Virtual Console title this week, sadly – the wait for Ufouria: The Saga and Aero the Acrobat 2, among others, continues.

WiiWare

My Aquarium 2 (500pts, Hudson) – Fresh from our revelation of the official website earlier, My Aquarium 2 emerges from the briny depths of Nintendo's WiiWare approval system to bring yet more aquatic action to the Wii. With brand new species and features, as well as the ability to transfer certain fish from its predecessor, My Aquarium 2 will no doubt float to the top of the WiiWare sales charts in no time. We'll have a full review soon, but in the meantime, check out our My Aquarium review to see if this kind of thing is worth raiding your treasure chest for.

Enjoy Your Massage! (500pts, Microforum) – You thought WiiWare couldn't get any juicier after Sexy Poker, but here comes a parade of anime ladies ready to let you press squares on their backs in a pre-determined order. Our upcoming review will let you know if this is worth your points or just a load of shiatsu.

DSiWare

TURN: The Lost Artifact (800pts, Creative Patterns) – A puzzle game that asks you to rotate the room to solve a series of mindbenders, we'll see if this is intriguing enough to enter the DSiWare puzzle pantheon in our upcoming review.

Absolute Chess (200pts, Tasuke) – Following the release of its disappointing Absolute Brickbuster, Tasuke is taking on another much-loved pastime: chess. With a challenge mode, learning aids including showing available moves and DS Download Play, read our upcoming review to see if this is checkmate or a rooking disaster.

Did It Myself ABC123 (200pts, Powerhead Games) – The last thing most people expected from the creators of Glow Artisan was a release aimed at pre-school children, but that's exactly what this is. Full of the things that kids love – apart from screaming and soiling themselves – this could be a worthwhile buy for DSi-owning 2-year olds or their parents. Find out in our review later this week.

Rhythm Core Alpha (500pts, SoftEgg Enterprises) – A live music performance tool, Rhythm Core Alpha may not be the most beautiful-looking DSiWare title (no, really) but hopefully it'll deliver in the sonic department. You'll know for sure later on this week.

Here's the press release for your digestion and subsequent comments:
