So, an old picture of an old accomplishment, but i wanted to talk about this. Less the accomplishment and more the thing it relates to.
#MarioKartDS had a really interesting idea that I am surprised hasn't carried over to later #MarioKart games. The single-player mission mode is essentially a series of driving challenges. Collect coins, drive through checkpoints, achieve X amount of power slides in a lap, etc.
Each level also has a pretty novel boss fight, like pushing a Bully out of an arena.
It is all quite creative and fun stuff, providing a means for players to develop skills that could help in the grand prix, other than doing time trials.
Though it will forever bother me that Mario Kart DS has 7 levels of missions, why not go up to at least 8? And call them worlds! But I digress.
Bottom line, I would love to see this mode make a come back at some point. But perhaps I am asking for too much.
