I'm seriously clueless as to why people complain about snaking. It's a technique that requires immense amounts of skill, and if you can't do it then why are you even complaining? If you can't be bothered to put in the effort that is required to be good at a game then you really have no say about those kind of things. It's not a glitch just because the creators didn't intend for it to be possible, it just happened to be.
I realize this isn't what the topic is about, but people bitching about snaking just gets on my nerves.
The snaking debate is old and thorny. It's kind of like this:
Yes, snaking was an intentional mechanic.
But the view against it is that it's like a fighting game that's so broken, that a single character with one move can beat everyone else in the game except for a mirror match against the same character using the same move. It's not about people being "too lazy to learn the game", which honestly, is a very condescending thing people who abuse snaking liked to say about those who didn't like it. People who are experts at the game didn't like snaking either, in concept.
It's more than it seems the MK team didn't realize how broken snaking was in the DS version, and didn't realize that people online would be drawn to the most broken tactic possible in order to rack up wins. They didn't realize that a snaking player was basically invincible against every other style of play on the relevant tracks. So the game online boiled down to "either play the game by doing NOTHING but snaking or don't play the game."
So. The general view against snaking is that it was a poorly though out mechanic regardless of how much skill was required to do it perfectly. Because it made the game play in a boring way that wasn't much like Mario Kart.
It's the same kind of debate you can find related to fighting games, as alluded above. Players who are experts with a particular broken character may not care if all they ever play is mirror matches of that character to see who can get the first hit in, then win. Everybody else may view that as a crappy situation though, and consider the game broken.
