Documents leaked by a former Rare employee have revealed an undiscovered Banjo Kazooie title for the Game Boy Colour. It was titled Banjo Kazooie: Grunty’s Curse and would later turn into Banjo Kazooie: Grunty’s Revenge which was released on the Game Boy Advance in 2003. The game’s script and concept were written up in 1999 and featured an evil blue Kazooie, a changed Bottles, and various levels that didn’t feature in Banjo Kazooie: Grunty’s Revenge.
Here’s A Look At The Cancelled Banjo Kazooie Game For Game Boy Colour

This should have never been canceled … It looks great and now I want to play it
did you not read it? it was revived as a gba game called gruntildas revenge. and how does it look fun if they showed no gameplay of it?
All of this RARE news and Banjo Kazooie articles is torture to the RARE/Banjo Kazooie fans.
Yeah will Nintendo’s the blame. Should had got them when owned 49% of Rare and then got out.
Why didn’t Nintendo buy Rare for the IPs!? Why, why, why!? I’m sick of the bullshit defense from Nintendo defenders that the talent was all gone. So fucking what!? You can always hire new talent, let the new Rare guys work with other dev teams on other games so they can get good at developing games, then have them work on the Rare IPs when they have improved their skills. Even the current IPs Nintendo has right now will eventually have new talent making them because Miyamoto, Sakurai, Aonuma, etc won’t be around forever. Miyamoto is already in the progress of grooming people to take his place & work on the franchises he’s made. He’s already done this for The Legend of Zelda franchise when he left Aonuma in charge after grooming him to take over the franchise.
But nope! They didn’t do that & instead let Microsoft buy the IPs & subsequently bury them with hack talent that apparently had zero respect for the IPs! *sigh* Letting Rare go was one of the beginning mistakes that led Nintendo to the crap they are in now with the Wii U & hardcore gamers. By hardcore, I mean people that play more than just one type of game or one type of brand, not those idiot brodude gamers that play nothing but violent video games.
Yeah will you know Nintendo is stupid with no common sense.
