Is it me or is 150cc a lot harder than in past MK games?
... At least you don't have to 3 star it to unlock characters..
I genuinely think it's the easiest it has ever been. I went through 150cc/mirror the last few days and on my first try got 3 stars on all of them but two cups.
Some stuff to keep in mind:
-Focus on acceleration, not speed. AI scales to it, and recovering from blue shells is more important.
-Unlike online players, the AI ALWAYS use their items. If you're in second and get a red shell, hold onto it until first blow their banana/green shell, but hold onto it if third gets a red shell to defend. This also includes the horn, the AI just blow it and don't even try to hit you. I've seen them use it, then get blue shelled afterwards.
-While they use items, it's on a delay. If the person in second isn't too hard behind, if you see someone else get a blue shell fall back so they get hit. But you can actually get very large leads over them, I've been hit by a blue shell/lightning combo and managed to not even come close to being passed.
-When you pass the finish line, everyone gets counted as finished. Even if one of the AI just got hit and technically finish much worse. Not really important for 3 stars since you always need first.
