Ugh, that game was broken beyond all belief. I can't think of a good thing to say about it other than it had Mario characters in it.
I played all Mario Karts.
The first Super Mario Kart is little hard to play but its fun cause everyone can win on it.
MK 64 was fun too.
Double Dash is ok,Not so fun like the other two but its enjoyable for a time.
I didn't had a way to play MKDS,just on emu but I'll definitely try it when I get the flashcard.
The Wii like I said is the best for me. It has online, many characters and many control options.
I can't fully enjoy MK7 cause I have problems with online (I think the electrical substation makes them).
Played it for 80 h+ and its still fun.
All what I am doing is getting coins for parts.
The game does not have the Mission Mode like the DS version so it kinda feels empty.
Just Grandprix and battles that are too easy.
No new features,just the gliding and underwater part.
Hope we can make our own grand prix n the Wii U version.
