(French Narrator from Spongebob): 1 Year Later...
What else can I say that hasn't already been said countless times before?
Even to this day it's still unreal to have them in Super Smash Bros Ultimate, Like it shouldn't be legally possible for them to crossover in anything official from Nintendo as their ties were (Apparently) severed and swept under the rug nearly 20 years ago as they are officially 1st Party Xbox characters under Microsoft...
And yet here they are.
Having them appear in a trailer with fellow Rareware characters in DK, Diddy Kong and King K. Rool like many have wanted, Seeing Microsoft in the title screen, Having the announcer announce their names on the fighter select screen, Having Spiral Mountain as their home stage to fight in. Having hear tracks and remixes including one from Grant Kirkhope himself and Having Banjo-Kazooie fight with fellow Nintendo All-Stars in Mario, Donkey Kong and Pikachu in each of their own home turf for me just feels so damn right and natural.
Banjo-Kazooie's long and difficult road to Smash that started out as an "All-Star" duo who seemed like a inevitable candidate that could have been in the beginning on the N64 and seemed only like a matter of time after they established themselves even further for them to join Melee or even Brawl, But were robbed of their chance as it was seen as good as dead the second Microsoft bought out Rare, But it was the ultimate "Underdog Story" that was 20 years in the making that made it even that much more sweeter and to me personally it was hands down, absolutely the greatest character reveal in Super Smash Bros history.
While we no longer have to speculate if Banjo-Kazooie will make it into Smash anymore, The good news is that we have yet to still see the inevitable positive effects of all this, Whether it's a Rare Replay Switch port, XBLA eShop ports, Remasters or a Reboot, Joining Smash was the adrenaline shot that this franchise needed to bring it back from the dead and based on the reception of their Smash debut, It's only a matter of time before they come out of hibernation and are back for good.
