It’s happening again. After four generations of capturing, breeding, training, and battling, you’d think that I and the rest of the world would cry uncle under the avalanche of Nintendo’s ever-growing menagerie of Pokémon. But that hasn’t happened yet, and Nintendo knows it, so here comes Pokémon Platinum (for Japan, at least).

Yep, Diamond & Pearl’s Sinnoh region -- and its attendant Pokémon -- are back, and so’s the nefarious Team Galactic. But for Platinum, the focus has shifted from Dialga and Palkia to a new legendary Pokémon: the Ghost/Dragon type Giratina, now sporting a demon caterpillar form. That’s not the only Pokémon to see changes, though. Nintendo’s expanded Sinnoh’s Pokédex for the return engagement, upping the initially available Pokémon to 210. Platinum throws a few new forms into the mix, too; the electric ghost Rotom can transmogrify into a variety of household and outdoor appliances. Fans, your prayers for a lawnmower Pokémon have been answered. Use it well.

Echoing previous Pokémon editions, Platinum’s interface is a step up from Diamond & Pearl, with sharper colors, new sprites and animations, and even the odd redone attack or two. Apparently tired of leaving the miracle of movement to their Pokémon, certain trainers get into the act as well, gesticulating wildly before releasing their pocket monsters for battle. And Platinum even offers new characters, including the elite (or so he claims) secret agent Handsome. This ever-modest investigator’s out to put a stop to Team Galactic (strange, since you’d think that everyone would’ve learned by now that all you need’s a plucky young kid and some Pokémon), and he makes the occasional cameo as you conduct your own investigations. Even Sinnoh itself has made a change for the colder, prompting the characters to don fashionable winter wear.

But Platinum’s head-turning addition is the so-called Torn World dungeon. Seemingly taking a fair share of its visual cues from Steel-type Pokémon Gym Leader Byron’s lift-centric abode, this world finds players spending a lot of time on 3D elevators while occasionally sticking to walls or moving at other odd angles. At one point, I even found myself feeling a little vertigo on my way down a waterfall when the camera shifted behind my character, giving a glimpse of the Torn World’s trippy aesthetics below. It’s easily the most creative dungeon featured in a Pokémon title to date. And when Giratina swoops in for its featured appearance, you won’t be disappointed -- the legendary caterpillar has nothing if not a flare for the dramatic.

But for all of the changes to the main quest, any hardcore Pokémon fan knows that all the good stuff comes after you best the Elite Four (the game’s final boss trainers). So what can you expect? Well, for one thing, Pokémon Emerald’s Battle Frontier (the huge facility with multiple Pokémon combat challenges/tourneys) makes a welcome return after a noticeable absence in Diamond & Pearl, as do the numerous combat challenges within. Your character’s rival trainer, the Gym Leaders, and the Elite Four, also put in additional appearances for the Battle Frontier, though with much stronger Pokémon. And for the Animal Crossing fan in all of us, players can decorate their own villa in much the same way as previous Pokémon entries, with certain characters paying you a visit as you steadily accrue more furniture.

Another Emerald feature making a welcome return: a much-improved Battle Recorder. Like StarCraft’s replay function, the Recorder lets you save completed Frontier and Wi-Fi battles for later viewing, presumably so that one or more of your friends can see how gangster your brand new Rotom-mower really is. Even better -- in a bit of a break from Nintendo’s traditional policy of making its online functionality as obtuse as possible -- you can upload or download battle videos relatively easily. Just hop on over to the greatly expanded Global Trade Center in Jubilife City and log on to your DS’ Wi-Fi Connection via one of the available terminals. The videos are sorted by popularity, and it’s fairly easy to pick out an interesting clip just by looking at thumbnails of the participating sides. For now, teams featuring legendary Pokémon figure heavily, but you can bet that weirder, more interesting battles will start to appear in the listings before long. Level 1 Baby Cup, anybody?

For those looking for more than just the most popular videos, though, the Battle Recorder also features a robust search engine. For example, you can seek out Pokémon-specific teams, meaning that your dreams of tracking down a Probopass-only confrontation may finally be within reach. And if you do happen to stumble upon that elusive Pokémon Valhalla, you can download the video with the stroke of the stylus to one of Platinum’s save slots and watch it to your heart’s content. It’s also possible to watch a friend’s battle, but expect to spend a lot of time inputting lengthy search codes.

Platinum offers other Wi-Fi enhancements, though some fans will be disappointed to discover the continued lack of random matchmaking. Trainers looking to settle grudges via Pokémon duels will have to make do with forums and friend codes rather than taking out their frustrations on some random schmuck’s Pikachu. But if you’re looking for random online hijinks in Platinum, there’s always the Wi-Fi Club. This mode allows players to venture into an arcade-like room featuring three minigames: a Wobbuffet balloon-pumping exercise, a Mime Jr. balancing endeavor, and a game where you use the stylus to toss cherries into a Swalot’s mouth. It’s easy to start one of these minigames, too -- just wander into one of the queues and wait while the game searches for other players. Just don’t go expecting anything deep. You’ll mostly find upgradeable stylus-driven "Touch Toys" (little doodads that create different effects and decorations within the Wi-Fi Club) as prizes, which are great for providing a bit of an amusing distraction, if nothing else.

Pokémon fans probably won’t be found wanting with Platinum. Even after you finish up the main quest, stop messing around with the Battle Recorder, and clear out the Battle Frontier, you’ve still got side quests and contests to keep you busy. And once you venture back down the Pokémon rabbit hole, you won’t be coming up again for a while.
