I would want either a remake of Chrono Trigger inthe same way Trials of Mana was redone (the base game and all charm is intact, but experienced in a new way) or a remaster compilation on Switch with Chrono Grigger, Chrono Cross, and a bonus translation of Radical Dreamers.
What I don't want is a remake like FFVII, where they use the base game but stray from the source material in a way that takes it in a new direction (though cross would set it up for aomethkng like this to be an alternative timeline, and maybe even set up for a new entry as a twist).
In any case, SE has been reviving old IPs and even expressed interest in making a new Mana game. This give me hope for any if these projects, or dare I say a completely new entry, to happen sometime soon. Not holding my breath, but the possibility is real.
