Since the soulslike community is quite diverse, I can imagine many different opinions to emerge here. Curious to hear your thoughts!
I’d take Sekiro 2 any day of the week. Bloodborne 2 would be amazing, but Sekiro, to me, is the pinnacle of the genre and has so much untapped potential that’s laying dormant. Bloodborne is too similar to your “standard” soulslike compared to Sekiro, even though I love Bloodborne as well.
In my opinion Bloodborne 2 and Demon Souls 2 are disqualified for being PS exclusives, and therefore I have no interest in them.
Sekiro I just didn’t like all that much, so I don’t really care for a Sekiro 2. I think From did well in making it; it just wasn’t my cup of tea.
For all my gripes with Dark Souls 3 it did tie up the series nicely with a nice bow, so I don’t really want any more Dark Souls games (If anything Dark Souls it would be a proper remaster of Dark Souls 2, but that is never happenening/that already happened and is called Elden Ring.)
So by default I guess the answer is Elden Ring. There are a bunch of story threads that I would like to know more about in Elden Ring (mainly The Gloam Eyed Queen and Melina (who is probably the prison/host for her) and what happens after the madness ending) and I like the game. But I think I’m pretty happy with where the game ended, and a sequel would need to choose which ending is canon (or be a prequel, I guess. The Shattering could be a fun time to explore) or it would need to be so distant from the game that we won’t hear anything about the questions raised in Elden Ring anyway (Dark Souls / Nightreign style).
If I could pick freely I think I would prefer that From takes the lessons they learned from Elden Ring and makes something new.
