It takes a few clicks to make a temporary email. It would just be pointless effort.
You can also make an email with fake/random data, verify the account and leave it.
And I don't really see how an eternal tutorial would help, really. Kikipro already made a great point: an extensive, obligatory tutorial would make the game extremely boring/exhaustive for newcomers.
How about we just let people who want to make alts make alts?
Email varification would be annoying.
Not all people have phones/would EVER want to use their phone number to sign up for something
Many people wouldn't want to go through a 30 minute tutorial
The current tutorial is enough- running/climbing are useless, considering there's youtube tutorials, and that most people don't run or climb anyway.
However! I do think that the tutorial should have several sections so that people who choose to do an extended tutorial can do so. For example: An in-game tutorial for the "youtube run".
But as far as using the tutorial to discourage alt creation, it's a bad idea.
Klein Bottles only have one surface so they are the easiest thing to clean
Whats even your problem with alts. Even if they get cheesy on a bet server you deserved to lose some tc, because you are then obviously to cocky and confident.
And whats the point of a longer tutorial. All you need to know is what joint does what, and you have to have some kind of understanding of physics.
Well in all honesty (this isn't really much of a legit reason not to have alts but its my reason I don't like most alts), I would rather know the real account name of those I defeat in battle. Its more of a pride thing in my case. Its not much of a moral win when you think you just beat a green belt when in actuality you beat a really good player who just happens to be disguised as a green belt. It also is part of a strategy, When you fight someone enough times you can make a mental list of how they usually play, Which you cant do if they keep changing accounts. If I have a feeling that the account im fighting is an alt that I haven't met before, I usually ask them of what their main account name is.
