I wasn't really all that enthralled by Black Butterfly, but I've heard I'm more likely to enjoy Ashen Hawk, haha. I just didn't really feel much for any of the characters in BB >.<
That's good that Nightshade is solid overall :3 I had heard quite a few people say they enjoyed every route, which seems to be a rare thing in otome, haha, so they must have done something right with it :D And I love it when yandere characters have a good reason behind why they are the way they are, so I'd probably love that route :3 It's been aaaaages since I played one where I genuinely enjoyed reading all the routes. I found finishing Collar x Malice quite painful cos I left the two characters I was least interested in until last, and their routes were even more boring than I anticipated >.<
I've not got 7'scarlet with it being a slightly newer title and my usual lack of disposable income, haha. Is it worth buying in a sale do you think? Not that I could even afford it then xD I'm not overly keen on the art either. "The bad end is bad in a different way sadly." That makes me curious, haha, but I guess I better not seek out spoilers in case I play it someday.
I've heard a lot of good stuff about Steam Prison, which I also don't have. I hadn't even heard of Monochrome Heaven, so that goes to show how far behind I am on keeping up with content >.<
I did quite enjoy Period Cube actually :3 It's been quite a while since I played it, and I can't remember whose route I enjoyed the most. If I'm remembering correctly, it wasn't who I thought would be my favourite (pretty sure it was a non-yandere)! MC was a bit annoying for me to self-insert with cos I've played plenty of MMOs xD
I think the Vita titles I own but haven't gotten around to playing yet are Code Realize + Norn9. The other stuff I haven't played yet in my backlog is on PC, which consists of Nightshade, Ashen Hawk, the new revamped Hakuoki games, BWS, Bad Medicine (though the English patch doesn't cover all routes and I was really bored with it anyway, haha), and a bunch of indie otome. I never did see past the base content of Mystic Messenger either! Just because the app became too large for my crappy phone to be able to download any updates >.< I had a founders pack for that with a physical box of stuff + lots of whatever the currency was for progression, and I don't have a clue what my account info I used would have been :(
Have an awesome weekend! :3
