I'm really excited for it on the principle of it being Star Fox. I know I will enjoy it to some degree. Adventures is the only game I don't enjoy that much, but it's not even a Star Fox game and more like a mediocre Zelda game.
However, I am not without my gripes and worries.
First off, no online. There's no excuse for that. The game was perfect for it. I don't get Miyamoto. Apparently giving a sequel to Luigi's Mansion an online mode made sense to him (even though NOBODY asked for that, people just wanted a new Luigi's Mansion adventure, period), but an online mode for a game about literal dogfights didn't. I'm sorry, but it's just stupid. This game should have online. Star Fox has a history of having multiplayer in every game sans the original and Adventures, and each time, it's been a natural fit for online, but the tech wasn't there. On Wii U though, that isn't a factor, so online is a logical progression for the series. BUT NOPE MIYAMOTO AND HIS DINOSAUR GAME DESIGN IDEOLOGIES GET IN THE WAY AGAIN. It's especially annoying since his excuse for it was "we wanted to focus on making the graphics impressive". I personally like how the game looks a lot stylistically, but objectively, the game doesn't look too amazing from a technical standpoint, it's leagues behind other Wii U titles like Mario Kart 8, Splatoon, and Smash - yet all of these games look better and STILL HAVE ONLINE.
Also, the game doesn't have proper co-op. It's been revealed that the co-op is more like the Co-Star mode in Super Mario Galaxy - Player 1 controls the vehicle's movement, Player 2 controls it's weapons. I can understand local co-op being difficult for this game because of how the Game Pad is used, but again, online! It would have been cool if you could a least do four player co-op with all four pilots, that would have been awesome.
I am also disappointed the game is pretty much Star Fox 64 2.0. It's jarring, since the last game was literally a remake of 64. The stories and characters are also one of the best aspects of the Star Fox games, so it's annoying stuff like Assault is likely retconned, as they had some awesome developments. I have created my own
Zelda-esque timeline for the Star Fox franchise, and I logically fit Zero into it, but I know Nintendo won't make this official.
I also was hoping for something akin to Assault, especially since it's the best game in the series, but I am not hurt too much by the lack of on foot (which by the way, DEBUTED IN 64, the game everyone loves so much!) missions, since I think the Landwalker is a good compromise. I enjoyed it a lot in Star Fox 2, and it looks fun here too.
There's more I could think of but at the end of the day, I know the game will be fun for what it is, I was just hoping it would be a bit more.
