Personally, graphics don't really mean much to me. That said, the remake I would like to see is Golden Sun 1&2 being in the same package. Past the start screen, you're given the choice whether to play Golden Sun or Golden Sun: The Lost Age. If you choose the latter, there could be a new option that would allow you to transfer Clear Data from the first game--one that doesn't require you entering a six-page password. You simply select the Clear Data you want to transfer, and that's it. Honestly, that was mine biggest qualm with the Wii U release of the Golden Sun games. You still had to type the damn password.
Again, until proven wrong, I'm calling shenanigans on the July 9th leak. Then again, I could see them announcing newcomers soon. I fancy a better demo of Smash Ultimate will be playable at the Tokyo Game Show in September. That said, announcing a newcomer beforehand, then adding said newcomer in the demo would naturally attract more attention. [Shrugs] At any rate, we'll know soon enough; just a few more days.
