This may be a dumb question but what's the draw of having the Wii version exactly?? Is it the same game in lower resolution?
"So four years ago, Yuji Naka and Prope revealed a game called Rodea the Sky Soldier for the Wii and 3DS. Since then, it’s undergone some pretty big changes as their collaborator, Kadokawa Games, seemingly took their sweet time publishing and advertising the game. While Yuji Naka said that the Wii version was finished, Kadokawa hadn’t given any updates on when it’d come out aside from them giving more information “in the near future” and the 3DS version supposedly still being worked on.
It wasn’t until late last year when the game was re-revealed that we’d actually get more information. It turned out that Kadokawa and Prope had pretty much been making an entirely new game for Wii U and 3DS, with them also releasing the original Wii game in a bundle with the Wii U version. As for the differences between the new and old versions: it seems like the original game is more arcadey and score-based, while the new game has a bigger focus on adventure and story"
