I feel Dew Prism/Threads of Fate deserves another shot. The original game was pretty good though not exactly groundbreaking, but the secret ending left the game on a cliffhanger.

I would love to see the Ivalice team do a follow up or at least a remaster of Vagrant Story.

If SE could team up with Mistwalker, I would love to see a third official Chrono entry, but like Lord Golbez, I would prefer something with a new cast and scenario that is loosely connected to the setting much like Chrono Cross.

If SE could team up with Monolith Soft, even if this winds up being a Switch exclusive, I would buy the system in a heartbeat for either a remake of Xenogears or a prequel/sequel, preferably one focused on Lacan and the Shevat-Solaris war from 500 years ago.

I also hope that SE may one day do remastered ports like the Romancing SaGa titles for Live a Live, Bahamut Lagoon, Treasure of the Rudras, and Einhander

Also, while it has been getting love from SE the past few years, I'd rather see SE release a collection of the Front Mission series instead of trying to make new entries.
