New Game+

[etony33]

Some Square-Enix games, such as Chrono Trigger, have a feature called New Game+. After you beat the game, you can opt to start a New Game+ instead of just simply a new game. The game begins as normal, except you retain your levels and inventory from your completed game.

This could work in PS4 with some save state hacking and walk through walls. As soon as Chaz and Alys begin the game in Piata, walk through the bottom wall and warp to The Edge. From there, go and fight the Profound Darkness. Plot items, such as Elsydeon and the rings, would be unavailable. Alys can equip the Moonslasher and Laconian Crown, though. You can stick some Sol and Star Dew into your inventory, as well as the Power Shield, Swift Helm, and Mahlay Shield, because you're going to need them.

Alys is not very helpful, of course. She has no healing techs, though she does have Saner, and the only skill she has that helps against PD is Vortex. Nobody knows Sar, making it very tough to recover from Megid.

Would this mean harder enemies or new content and side quests?

Not necessarily. Chrono Trigger had 13 different endings, for instance. If you consider the warp point through the wall in Piata to be an actual portal, you could kind of use your imagination (example: Profound Darkness is dead, but Zio is not. You never rescued Demi or stopped the blizzard on Dezolis. It could make for some interesting combinations)
