Same here. Until someone mentioned it on here, I didn't even know what Style Savvy was so I looked it up. It's literally a simulation game for the DS.
I mean, the game was on DS and hasn't been seen since October 2008, not sure why they want to promote it; it was on the Wii U for Virtual Console, but promoting something on a console that Nintendo doesn't care about anymore seems odd... unless the Style Savvy soundtrack is located in the "Others" music selection menu, because Snipperclips, Monster Hunter, Fossil Fighters, and a few others have soundtrack in there without a representing stage or character. Style Savvy wasn't released in the EU and US until a year after the Japan's release. Hell, I played and got so many DS games back then and still never heard of Style Savvy until now. lol
Doesn't seem popular and relevant if no one on here's heard of it until now, and the game isn't that relevant because it was a game on the DS in 2008. I looked up the details and it only sold 2.09 million, while Super Mario RPG sold 7.42 million. SMRPG is relevant because it was on the SNES Classic in 2017, and Style Savvy was released on the Wii U Virtual Console in 2016. In total with the DS and Wii U combined, only 2 million sales; for the SNES Classic, about 5.28 million sales. It seems that the SNES Classic is more relevant, appealing, and popular compared to a simulation game from the DS.
But why promote a DS game from 2008? That's something I don't understand.
