Well, at least with Shiho, it looks like you have to beat the game with her three times over anyway if you want to fully complete her album, since it looks like there are alternate versions of her ending picture. So you could always pick up those post-credits pictures on a replay to get the alternate endings. Looks like Yukiko also has to be done three times over. Kinda tedious. I don't mind the scenes that have alternate versions for Reika and Shouko since they're at the beginning of the game and can be picked up regardless of who you focus on, but I wish they didn't put scenes like those near the end.
Anyway, I have a few things about the game I'm curious about that maybe you or Filler or anybody else who's played the game can answer. For those who haven't, here's fair warning that it may be a bit spoiler-y.
Does anybody know what the whole "Milk" thing is about? Is this some kind of wordplay lost in translation? As best as I can tell, it sounds like they actually pronounce the English word "milk", and it doesn't seem like the Japanese word for "milk" is anything like "Rumi" anyway. I wonder if maybe it's a matter of the characters being backwards, like "miru"? And maybe the "ku" is from the honorific "kun"? Like "Miru-kun"?
Shiho says that she's seeing someone and that it's somebody the main character has already met, but that plot point seems to get completely dropped later. I mean, the only guys you've really met at that point are Daisuke and your dad. It's not Daisuke, and I hope Yusuke isn't getting his dad's sloppy seconds, haha. But I was thinking maybe she was actually talking about the restaurant itself? She compares the restaurant to a lover near the end of the game, so maybe she was just speaking figuratively.
And finally, does anybody know who Yukiko, Rumi, and Yusuke are dressed up as in Yukiko's ending? If the outfits aren't completely made up that is. Yukiko obviously dresses up as Haohmaru from Samurai Shodown in the game, and I'm guessing Rumi's Comiket cosplay is a reference to Darkstalkers. There's also a guy in the Comiket background that looks like Terry Bogard. So I figure the chances are decent that the ending is referencing something real too, and I could swear that Yukiko's outfit looks familiar. There's a focus on fighting game fandom mid-game, but I kind of doubt they're dressed up as fighting game characters in the ending since Yukiko says that Rumi is the princess and Yusuke is the hero. An RPG seems more likely.
