In testing what was the result of logging a permanent global state for every playthrough? How are they indexed, and does it generate bloat or loading slowdown? At 10 concurrent playthroughs? 100? 1000? 10,000? I'm curious as to how complete the QC process is.

IDK the details but it's not like you need ALL the playthroughs data in memory or in process, since there is only a single playthrough being run at any given time.

Does that mean that you won't be able to change your choices when you load a game? If the ID remains the same and the global database remembers previous choices...

Delta, this is seriously awesome if I'm right in how I interpreted your blog post. This is actually very similar in result to the "awesome idea" I thought up over in the main public discussion forum, though the implimentation is different (though I doubt you had that in mind when you started working on this, and your work probably predated my inspiration anyway).

Just to be clear, this means I could start a readback while at the final ending to the game and just basically read through the whole thing from the very beginning to there again without having to stop and make the choices myself, right?

If so, then I don't care that I have to do a full playthrough first, I can just save at that point and revisit the various paths this way instead of the 'alternate bonus mode' I thought up! I'm seriously excited about this!

If you want to try new choices you could just start a new playthrough. It's not like KS only saves one playthrough at a time anyway.

Well...

delta wrote:I consider the text backlog in KS a form of protagonist memory, and memory is immutable. When you roll back, you don't "roll back an interpreter", you retread what you have already seen. This implies not being able to redo choices...

... It still allowed rollback (because it is indeed a nice thing to have), but it blocked rollback after choice points, yo you could never roll back beyond a choice. That way, you could not change a choice you had previously made, and if you wanted to access the text displayed before rollback was blocked, you had readback available.

...(and the method described above is described as "readback" in contrast to that).

This means that you can only rollback to the last choice you made, and play the game from there. Anything beyond that is blocked, and you can only read that in readback. Readback shows a list of all the dialogue that came on the screen during the playthrough. In other words, you don't see the text and characters live in readback, only in rollback. So your "watch the game without making any choices" thing isn't possible with this implementation.

Actually:

That way, you could not change a choice you had previously made, and if you wanted to access the text displayed before rollback was blocked, you had readback available. I never found this completely satisfactory, because it was an obvious crutch. I felt that the version I want was full rollback without the ability to retake choices. So I went and did that.

And earlier:

Delta wrote:Ren'Py, the engine we are using, solves the problem in a different way, which is calls "rollback" (and the method described above is described as "readback" in contrast to that). Rollback lets you "roll back" the whole interpreter state to a previous point. This is definitely the technically superior method, and a lot harder to implement, and it's one of Ren'Py's selling points. The reader can not only read the prior text, but they also get context - the whole screen, with character expressions, sounds, animation, everything.

Emphasis mine. So I still think Delta meant that we'll be able to rollback and review the entire thing, just not being able to retake the choices and being stuck on the path we chose (which is close to what I was going for in my idea anyway).

I'm guessing you mean the common VN playing strategy of saving before choice points? You can choose differently upon loading a game, retaking choices already made in a given playthrough is the only thing that's blocked.

Currently you can't roll back past the Act titlecards. Anyway, even if you could, rolling back tens of thousands of lines seems a pretty impractical thing to do.

Just do what you think is best, Devs. We'll enjoy it all the same.

Most of us.

Thanks for the clarification. Still, being able to watch back individual acts via this system is a really cool bonus anyway.

I hope that last bit wasn't meant to be a shot at me... I'd enjoy KS just the same even without ANY sort of 'readback' or 'rollback' system, I just think it's an awesome bonus on an already kickass deal.

Some people just can't be pleased, lad.

delta wrote:Enough with the good news, here's some stuff you don't care about.

Oh my god you're right, it is something I don't care about.
Okay, maybe I care about it a little bit.

And simply yes, the strategy of saving before every choice is the simplest and most useful of any VN strategy.
