The cute is overwhelming
Good Smile, the company responsible for Nendoroids, has been involved in helping to create a game based on those Nendoroids to celebrate it's 10th anniversary.
Released in February for the PSP: Nendoroid Generation.
All I can say is, "Hhhnnnnnnggggg! I want it! Oh, god I want this game." Then I remember I live outside Japan and the chance of this getting a commercial translation and release State-side is remote, to say the least.
But at least I can enjoy videos like (might be spoilery) this.
Also, a video featuring all the playable characters Special Attacks and Buffs.*
Now if you'll excuse me, I need suck a lemon or something before 'Teh Cute' sends me into shock.
*EDIT: That isn't all of the attacks and buffs, and I don't think this is either. It does show most of them, including some unique boss ones. It also shows some of the weapons the characters can earn along with different outfits by playing the dance-mode minigame. Though the mini game is all about preparation rather than control. You choose the characters to do a certain dance and depending on their mood, whether they like that dance, and each other determines how well they perform. So that means you get to sit back and enjoy watching them dance rather than focusing on which buttons to press and missing all the fun.
