I'll assume anyone reading has played/watched the original Steins;Gate. With that being said, this game is a grief and trauma story with a science fiction twist. Which I think is done really well. It's less focused, but because the writing is better, I think it goes to higher highs than the original often. And I find it more interesting than just "time travel story that is really good and has consequence" which the original goes for.

Main characters aren't just fun tropes anymore. The game shifting between perspectives is an amazing addition. The non-canon endings don't just diverge into "For this ending, you partner up with this woman" like in the original. One ending doesn't even have Okabe in it.

If you like the idea of characters sharing grief and trauma and overcoming it together, I highly recommend it. It was a pleasant surprise for me, especially after hearing how "it's worse than the original".
