You have probably noticed by now, but almost all the characters are returning, so no worries about that. The pacing has to be sped up a little, although I shall endeavor to make the world-building better than before.
All in all, please do enjoy your reading.
...though I'm curious. How would you compare AC to some of the other KanColle stories out there?
Oh yes, I have noticed, having just caught up in the reboot, and I am very glad to see familiar faces. I was actually worried there.
Enjoying, check, though to be honest I must agree with parts of another review in that I will actually miss Magician, and for somewhat similar reasons.
Ooh, comparisons are difficult, but I shall give it my best shot, while trying (and failing) at relative brevity...
The simplest point I could make is that I find incorporating many game mechanics (level, resources, expeditions, scrapping) to be typically jarring and immersion breaking, and those are very common elements. There's also a great deal of reliance on established and limited canon combat methods, or just blatantly silly-feeling invented ones, and a similar approach to the creation of kanmusu and abyssals. While I love a good AI, I think the spiritual-magical interpretation just fits better, and I prefer the approach that Abyssals aren't merely fallen/darkly-reflected kanmusu. It gives them more potential depth, I feel, likely at the cost of some tragic value, but I'm okay with that. This story (including by extension the reboot) just has a very grounded and real-feeling set of magical/physical 'laws' governing it, in that science and Abyssal magic seem fleshed out into full systems behind the scenes, and a solid feel of complex interaction, politically and socially, on both sides of the metaphorical aisle, both of which I found largely lacking elsewhere. In short, only this and one or two others left me saying "Yes moar naow." and refreshing ff.net daily, with attachment to characters and appreciation of setting, and nary a meta-cringe-worthy moment to be found.
Okay, last thing, one I've only seen done in a few total stories. It appears you have believably dramatically expanded the world of both magic and technology beyond magical floating girls with guns versus magical floating horrorgirls with guns, to the point that it feels like a living, evolving world on all sides, rather than a game-esque static war scenario. Or maybe I'm just a sucker for R&D, who knows!
I hope that answered the question and didn't veer too terribly off track...? Also, apologies for the ridiculous post length.
Edit: Oh sure, let's make it longer. I noticed another reply in there, and personally I like the not-so-different-from-human approach. Just had to say it.
