I like Double Dash a lot. It was just a more refined, crazier version of Mario Kart 64. After that they started to feel kind of lazy to me. I think there are some really obvious cool features they could put into Mario Kart that they just don't. How do they not have item selection? Why is the battle mode always so half assed?
I honestly can't tell. I have the best multiplayer memories from Double Dash and MK64 but MK DS had this amazing challenge mode and I really love the motion controls in MKWii and the online and general variety in MK7. Then there's the super crazy nostalgia for the original SMK. The only one I spent little time with was Super Circuit because I joined the GBA train very late.
Super Mario Kart was my first, therefore it was the best. Some fun was had with Mario Kart 64. Maybe I should have given Double Dash a better chance, but when renting it and playing with my friends we all agreed it was icky. Since then I took a break from Mario Kart until I briefly played 7. I'm considering picking up Mario Kart 8, but hearing how they dropped the ball on battle mode is a bummer.
I've only played Mario Kart Wii, DS and 3DS. I hated Mario Kart DS (mostly due to the controls). I probably had the most fun playing Mario Kart Wii with friends. But I voted for Mario Kart 7 for the 3DS because it is the only one that I enjoyed enough to try and unlock almsot everything in it.
Wow, I wasn't expecting to see the Double Dash love. Is that the only Mario Kart to feature character specific power-ups? I loved that part of the game.
The Gamecube was the last Nintendo console I owned, so I don't have much experience with the series past that. Though I did recently play the arcade version and thought it was excellent. Lots of rubber banding though.
The first one. Everything else has seemed derivative. I'd like to see them revamp the powers. Stuff like the Green Shells and Banana peels are a consistent main stay and they probably shouldn't be.
One thing that has turned me off for awhile is their insistence that you go through the easy 50cc tracks. Do they expect people to say "Great, I lapped everybody on every course, and I'm new to the game, I am amazing, thank you Nintendo!!!! Fan for life!".
I'll be honest though, their competition, the Sonics, Crash Bandicoots, Shreks of this world aren't exactly making a case for Nintendo needing to do anything different.
