I just remembered that the last game I got 100% achievement completion before picking up Analogue: A Hate Story was about two months ago, with Acceleration of Suguri X-Edition on PlayStation Network. This one, being a doujin fighting game instead of a visual novel like Analogue, took me a bit more time to complete. It’s still moderately easy to get 100% in a short amount of time, so long as you know what you’re doing. I think one of the arcade modes has a double-secret boss à la Dural from Virtua Fighter, but you don’t necessarily have to beat it to win.

I’m not making that big a deal out of this one because most of this info was up on PS3Trophies.org a while ago, but it’s also here on my website if you want to read up on it.
