I was just giving him an easy explanation, we want him to like the game and not get overwhelmed, and I know that Sora can also wield 2 blades, but in an interview by the company it was explicitly said that what set Roxas apart from the two of them is that he's ambidextrous.
They have to make small differences between the 3, they might have strong connections with each other but they are different people.
As much as they all fuss about Roxas being the same as Sora we all saw how different he was from him.
Yes, he had his moments but he was made into a different entity just like Xion was.
If you put attention to the "War of the Keyblades" they all take those 3 blades, so the assumption is that those will be their final blades since they are competing to become a Keyblade Master.
Not that I'm trying to argue, but I'm really picky on my information about the next KH game.
So.. if you're picky.. why is your infomation based on assumptions and false information?
First of all.. unless you can provide a link, I can find no information anywhere about Roxas' ambidexterity "separating him from Sora." Especially since Sora is ambidextrous in 3 of his 4 drive forms.
Also.. obviously the 3 aren't carbon-copies of Sora/Riku/Kairi. And even thinking I was implying that would be pretty sad. Obviously there's gonna be differences.. but their personalities are similar, and there could be other, as of yet unknown, connections.
And the "Keyblade Wars", the end of KH2, is actually called "The Gathering". And you need to stop assuming so much.. they aren't "competing" to become Keyblade Masters.. if you've seen the Birth By Sleep video, the secret ending of KH2: Final Mix+, you'll see they are actually preparing to fight Xehanort and his apprentice, Venitas. And just because they pick up a weapon doesn't mean it's their final/ultimate weapon. It simply shows their connection to the KH characters that use those weapons during KH1/KH2. The BBS game was barely in development when KH2 and 'The Gathering' video were released.
So, if you wanna be picky about info.. stop assuming non-factual, very potentially false information.
