RED_NOVA'S PROFILE

It can depend on what you include in "other things" you plan to recycle. If you've made everything yourself and/or used publicly available assets, then you SHOULD reuse them. Hell, you don't even need the game to be canceled to reuse them, as noted by Sgt's Pokemon example. It's already been noted that assets commissioned from others don't fall under the same lax ruleset, but that's something you're gonna have to work out with the original creators themselves.

Also, don't feel obligated to tie it to Legacy Saga. You can literally just copy/paste the map from Legacy Saga to your new game and call it a day. If you're concerned about players seeing this and recognizing the map from Legacy Saga, then there are things you can do to cover it up, such as giving it a new tileset, rearranging B level tiles, etc. Even a simple tint change can give the same map a radically different look and feel to it.

Don't let the imaginary stigma from ignorant gamers fool you: Recycling assets is the sign of a smart developer, not a lazy one.

Noice

I think Dark Souls would make a for a good film adaptation if the director uses The Revenant as inspiration. You could have the quiet moments where you can take in the scenery of each area by following the Chosen Undead, and switch perspectives to one or two NPCs and follow their questlines for more dialogue-heavy scenes.

Personally, I'd like to see the questline that was cut from the final game where Oscar escapes the asylum with the chosen undead. Following their journeys through the world would make for an interesting alternate timeline that can switch between perspectives as needed to maintain a good pace for the film. That could bring in newcomers to the series without alienating the fans for breaking cannon. "Time is convoluted in Lordran" and all that.

This video recreates the questline using cut voice lines from Oscar:

Nice! It's good to see this game reaching a wider audience.
