Well, I enjoyed Double Dash so much as a kid. I just loved the new tracks and jazzy tunes that Mario Kart 64 didn't have. I am one of those who believes that Mario Kart 64 isn't the best Mario Kart although it was great. What I really loved about Double Dash was the double character idea, the specials that have just recently gone missing, the ability to dodge red shells and Spiny shells just by drifting fast enough, and it was just overall a solid game.
The character roster was a huge improvement for the time and something about Mario Kart 7 that troubles me is that Waluwigi has a stage but not a character choice... that's too weird. I still love MK7 but it wasn't as innovative as Double Dash, TO A CERTAIN DEGREE. I know the second screen is great, the para-glider was fantastic, but the item choice was kind of lacking and some physics are just waaaay off. For instance, driving into the grass causes almost immediate slowdown unless you have your "off road" on the max level. I hope they bring back the double kart and specials in the Wii U Mario Kart, which I hope will be named Mario Kart Ultra. That'd be a sweet and fitting name.
Finally a real response! ^_^
Yeah I definitely agree that 64 is not he best of em. Honestly the newer ones are so much better in pretty much everyway. My biggest quip about 64 is it's tracks are so bland. All you're doing much of the time is holding down the A button and not much else. Even in the newer games, I'm not a fan of playing most N64 tracks, though they're made a bit better with coins, tricks, gliding n such adding more depth to the tracks and increasing player input. But anywho, let's get back to DD!
The double character thing is the games gimmick, much like gliding n underwater portions are in MK7. They don't really change the core gameplay much if at all (which is definitely a good thing) and are really just there to differentiate the game from others in the series. Basically they don't help any one MK be better or worse than another. No specials yes, though honestly I say this helps balance the game, but regardless MK7 has many other features that more than make up for this (customizable karts, online). I suppose it's kinda kewl that you can dodge red shells like that, though there are ways to avoid them in MK7 too, but they're easy enough to block just by holding an item behind you. It's way more important that you can avoid blue shells thanks to the second screen showing you when someone has one so you can temporarily drop back into second. And yeah every MK is a solid game. :P
Yeah idk what Nintendo was thinking with the character roster, but honestly it's not that big of a deal. They could be stick figures and the game would still have the same great gameplay. And when you say innovative, what do you mean exactly? Hopefully not just having a new feature first that the new versions still have. :P
What's the item selection missing asside from super op junk? Has all the trademark MK items along with new, balanced ones. Pyshics are something that just has to be gotten used to as it varies from game to game, sometimes even from games of the same series. You shouldn't need to go off road too often, and it kinda has to slow you down instantly otherwise a lotta shortcuts would be too easily accessed.
Mario Kart U (which is likely to be it's name unfortunately), could easily be the best one yet! Can't wait to see what it looks like!
