Metroid Prime.

Star Fox sales haven't met expectations because they haven't put out a worthwhile game bearing that title since Star Fox 64. Star Fox on SNES and Star Fox 64 are both great games, and were successful for Nintendo.

If they want to do Star Fox RIGHT, they will do Star Fox the only way it SHOULD be done, which is like those games. Star Fox is an on-rails arcade style shooter. That's what it's supposed to be, and that's what it should be. Anything else is about as pointless as making an R-Type game where you get out of the ship and run around as the pilot.

They could do an AMAZING SF game on Wii U, if they really wanted to. But they need to get off their asses and do games like that, F-Zero, and Wave Race for Wii U in-house. And personally, I really want to see all three on Wii U eventually.

Not sure if this suggestion is blasphemy, but I feel that Nintendo would also need to get rid of the animals as well and more towards more traditional sci fi characters. Whether they turn them into humans or aliens that resemble the creatures they are named from, I do think that the animal aspect would limit the seriousness of the game.

Not that you necisarrily did, but I find it odd that people always aknowledge Metroid Prime as being "the return of Metroid" after it's long hiatus, even though NIntenod themselves developed Metroid Fusion for GBA, and it released exactly the same day as Prime did on GC. Honestly, Fusion was a really good game, despite it's linear nature (something that cannot be said for Other M), and if anything, THAT was the true return of Metroid (seeing as it's literally titled Metroid 4), whereas Prime was a weird experiment that somehow wound up working really well.

Just saying....it's odd to me that people give Retro and Prime so much credit, when Nintendo themselves kicked ass with Metroid on GBA with Fusion and Zero Mission. Personally, I'd love to see another actual 2D Metroid game, in the vein of Super and Zero Mission.

You got me there but can you prove that it's not an exception ? 

What do u mean by worthwhile?  Worth the time to play, worth the money or worth developing?

Eh. I like the idea of Star Fox being a furry parody of the typical space opera. One filled with cheesy and memorable one-liners, and featuring a comically overdramatic story.

Why ofcourse all of the above silly.

The most important of all being worth developing. Nobody wants a solution to where there is no problem to begin with and just like it, nobody wants a game that everyone doesn't care about. 

Fusion was a great game that was critically acclaimed and sold well, along with Zero Mission.

However, Prime was even more well-recieved and became the best-selling game in the whole series. And much was made about how it was arguably more true to Super Metroid's design than Fusion was.
