I'm gonna have so much fun with this once it's released (hopefully I get some time to order it early...the next few months tend to be rough on my credit card due to holidays and October having several subscriptions up for renewal).
And a thought that just popped into my mind because, well, I tend to have interesting or hilarious wanderings (crack or possibilities) when I start thinking about Touhou. As said by other people, there's a low likelyhood of a lot of earlier fighting game characters appearing due to the lack of involvement with the religious conflict. So now my mind just went over and thought, "If that's so, as it probably is, Yukari is going to be watching the whole thing via a gap with some popcorn she procured from the outside!"
