If the classic game, Tales of the Abyss gets a reboot, I like to say a few things it might include. My memory is "a little hazy", so I'm basing information from its TV tropes page.

 

• For any reason, Tear from the original game sending vague visions to herself in a parallel timeline. She might receive the visions at the point where she breaks into the fon Fabre manor.
• Because of the visions, Tear will share the role of main protagonist with Luke. Not to mention that she'll interpret them as technically predictions of the future.
• Make pre-haircut Luke SLIGHTLY less jerkish than he was in the original game.
• Tear's vision induced actions will cause the people to abandon the score much earlier.
• Upon arrival at Akzeriuth, Tear will suggest evacuating the people, because of a vision of its destruction. Because of this, nobody was killed or injured. And Van and/or Asch will question how most of the party knew when to evacuate the inhabitants.
• The party will hold Tear partially responsible for Akzeriuth's destruction. Because she wouldn't tell them why she was trying to assassinate Van.
• Jade would have a bit more personality than in the original game. And that means less sarcasm.
• Anise's status as a spy for Mohs would be revealed much earlier. What happens to her family spreads like gossip. So a few (if not some) characters will privately tell her "I know who you are". Namely, Tear, Asch, Arietta, and possibly Jade, before the entire party learn that. That would be one of the differences between the original and reboot.
• A private conversation between Tear and Anise would cause a vision of Ion dying shortly after the entire party learning the latter's secret.
• Asch would be a little hostile towards Anise, since he knows her secret. Threatens to tell everyone he comes across the truth about her, if anything happens to Guy or Natalia.
• Tear at some point would completely lose faith in Mohs. Saying either "I don't know why I keep justifying your actions... you're nuts". "I don't know why I thought it would be a good idea to work for you. But that's a mistake I won't make again". And if he's defeated by either getting imprisoned, left for dead, or killed, she might respond to him begging for his life with this. "Bringer of prosperity, no. You, YES".
• Continuing from above, Mohs might lose his good publicity once EVERYBODY see's him for what he is. To the point where he loses the respect of his soldiers.
• Guy may confront Herzog about his family's death. And maybe ask if it's because the score said so, or if it was personal.

That's all I got. Feel free to post your ideas on what differences the reboot might include.

I think it would be better if the game got a sequel because of what happens at the end of the game.

Its been years. I don't think Tales of the Abyss will get a sequel.

It took years since kid Icarus got a sequel so it's still possible

Probably because the popularity of Kid Icarus increased due to Super Smash Bros. Brawl.

 

BTW, some (if not most) of the differences I listed are inspired by The Walking Dead (topic of Lee's past), Mortal Kombat 9, and maybe Tales from the Borderlands. And I like to see this exchange in a private conversation between Asch and Anise.

 

Asch: I know who you are, Anise. And I know you're spying for Mohs. So if anything happens to Guy, or Natalia, you watch your back. Otherwise I might tell everyone along the way, the truth about you. Maybe the group your spying on, included.

 

Anise: You wouldn't.

 

Asch: I would.

 

Anise: (laughs uncomfortably) Of course I'll make sure nothing happens to these two. And I won't tell Mohs that you know my secret.
