Which version? I did a major rebalance after the initial release which changed up mercy's content and added her yacht sex scenes and some changes with batgirl. Then went on to add Artemis and Cheshire with their unlock route. The game is a work in progress which I intend to tailor to the community regarding content and gameplay. I'd love to hear any detailed criticism if you have a discord.
it "is" all content from SU, until it isn't.
Want new art, new assets, new gameplay?

Do you actually like the legion heists? Glamor slam lineup planning? Meta Bordello? Any assigning micromanaging grind? Unlocking raven? Deus ex machina addons of blackfire, terra, starfire, cheshire, miss martian, etc. ?
No?

In my edition you are the PC "lex luthor" who is re-establishing his criminal empire via rebuilding the legion and managing the glamor slam (as owner, lineup is for the help), exploiting your gamable mind control device as a reason to capture and train heroines and control or hire henchwomen. Shenanigans ensue.
Played the current version (at least the one in the OP).
The writing feels lacking, Sunset at least puts effort into making the game coherent with itself and the DC canon in regards to personalities. Sure people act out of character to varying degrees, but in ST I felt these moments far more common and instead the writing feels more like an average trainer than a DC game.
The art, you can tell when an edited asset appears, but all things considered, they are solid. I again reinforce my opinion that your skills would be better served modding the actual game, you could add more depth and interactions to scenes beyond the scope of what Sunset plans instead of starting from scratch and having to cover ground that has already been written and coded.
Storywise is where I feel ST is at its weakest, there's no heroines in the Glamour Slam, no Meta Bordello (and all good scenes in it), no overarching plot with a Braniac, Grodd, Deathstroke, Joker, etc. You might feel like those are unnecessary from a porn perspective, but they frame the gameplay and story without losing any time for the player because all actions ultimately lead to porn and always keep them moving from one step to the next.
It's SU, except missing a lot of what made it great in first place. Sure removing the grind is good, but not at the price of losing the main plot, Meta Bordello and Glamour Slam.
Instead, if you wish to really create something great, I would either go for modding or make something new to stand on its own. Make Lex join the JL and corrupt them from within, run a smear campaign by lewding the heroines, or even remove Lex completely and make a game with a new MC and story.
