Perhaps, but since R.O.B. is Nintendo's property, he could still be considered. The other possible option for a medium-sized heavyweight would be Silver Luigi (to go alongside Gold Mario), but some people would consider that to be lazy.
To be honest, as much as I would like to see King K. Rool, I've had to lower my expectations, knowing that he hasn't been in a Mario spin-off title since Mario Super Sluggers.
Anyway, in terms of the details on some of my roster inputs...
The inclusion of Honey Queen and Pom Pom is so that we...
Knowing Nintendo, it will most likely stick with its own property, which has been evidenced with MK8 and MK8DX; all the guest characters came from franchises that Nintendo has the full rights to.
Anyway, in terms of a roster that would feel realistic, the following would be one example...
And that can probably explain why Mario Kart 7 and Mario Kart 8 implemented a body size system. That way, any character can use any vehicle body without looking too awkward.
I still remember hearing that SNES The Lion King was intentionally made to be hard, all in an attempt to make people buy that game. Likewise, while Final Fantasy VII is known for being among the greatest games in the PS1 era, it's absolutely scandalous that Square Enix decided to make the Ruby...
It definitely makes you wonder what would've happened if N64 Bowser's Castle was ever available in Mario Kart Tour. It probably would've gotten in over SNES Bowser Castle 3 in the final Booster Course Pass wave.
But now that the pass is complete, all that we can really do is move forward.
It was a wild ride while it lasted, but much like with Super Smash Bros. Ultimate's DLC, Mario Kart 8 Deluxe has reached the end of the road with its DLC. I was disappointed that some of my favorite courses didn't make the cut in the Booster Course Pass, but perhaps the next planned installment...
Well, when you think it over, when you look back at Mario Kart 7, there really isn't any real penalty for taking the off-road shortcut without a speed boost, all thanks to the glider ramp.
After looking at the artworks, it's not often that you see Ashley outside of her comfort zone. But I suppose her typical outfit is not meant for tropical environments.
I guess the reason why I was thinking Wii Rainbow Road was because the first half of the Booster Course Pass ended with 3DS Rainbow Road. Surely the second half should finish the same way as the first half.
