This is the cheapest pre order price I've seen for this game and it has 9% quidco on top of that which makes it roughly £20.93. This is a really good deal.
EDIT: you can also get it for the same amount at game.co.uk BUT you will get a FREE mini figure of Giratina! It'll probably be worth something in a couple years so thats a big bonus!
if you still want to order it from gameplay go here:http://shop.gameplay.co.uk/webstore/productpage.asp?productcode=DS2158
if not click go to deal!
Gameplay's Product info;
Pokemon Platinum for Nintendo DS features a sweeping new adventure, set in the Sinnoh region of the Pok?n world, packed with new features - such as new ways to play online at the Wi-Fi Plaza over the Nintendo Wi-Fi connection and the ability to save your greatest victories in the Vs. Recorder - that will electrify fans of the Pok?n series. A brand new Distortion World, governed by neither time nor space, also emerges, which provides a whole new gameplay challenge!
The epic story of Pok?n Platinum Version revolves around the legendary Renegade Pok?n, Giratina, appearing in its new Forme, the Origin Forme. Many other Legendary Pok?n are featured and can be captured in Pok?n Platinum Version - from Dialga and Palkia, to the powerful Lake trio of Uxie, Azelf and Mesprit
Perhaps most excitingly of all, one of the rarest and most popular Pok?n, Shaymin, available only on Pok?n Diamond Version and Pok?n Pearl Version through special events* appears in a new Forme in Pok?n Platinum Version. Transfer Shaymin from your Pok?n Diamond Version or Pok?n Pearl Version game to your copy of Pok?n Platinum Version to discover the never before seen Sky Forme, with a new appearance, new attributes and special powers.
Your heroes appear in a new, special winter wardrobe in order to survive the freezing cold of wintry Sinnoh in Pok?n Platinum for Nintendo DS. As you follow the main quest to put a stop to the sinister Team Galactic, completing side missions and contests along the way, you will - of course - engage in some serious battles...
And when it comes to battling, Pok?n Platinum on DS certainly packs a punch!
Pokemon Platinum features an all-new Battle Frontier, a special building packed with challenges and tournaments, is accessible after defeating the 'Elite Four' and the Pok?n League Champion - the game's final boss Trainers - and gaining a ferry ticket to the Fight Area. Not only are the final bosses harder to beat than ever before, but once you've overcome them and entered the Battle Frontier, you'll find the fighting has only just begun! The Battle Frontier contains five different Battle facilities, with each facility awarding Battle Points that can be traded for fantastic prizes.
In addition, the Global Trade Station from Pok?n Diamond Version and Pok?n Pearl Version has been expanded and renamed the Global Terminal, where you can check out other people's battles. Battle Videos are listed by popularity, so you can easily locate great content! You can save Battle Frontier and Wi-Fi battles via the Vs. Recorder, so that you can connect with Pok?n fans around the world and interact in new ways. Re-live your victories - or use them to gloat and provoke your friends into online battle!
Pok?n Platinum for Nintendo DS is designed to make online play as simple and exciting as possible. In the basement of every Pok?n Center is a Wi-Fi Plaza where up to 20 players can connect wirelessly and play games together in real-time. As well as trading and doing battle with friends with whom you have exchanged Friend Codes, there are a number of mini-games available to play together in the Wi-Fi Club.
