Back when I decided to do a little platinum trophy number boost, I bought One Night Stand in the PSN sale for relatively cheap, you may remember I wrote a review on it. I had chosen One Night Stand, among a few others, as it was reported to be a quick platinum, and when I say quick, I mean quick. I managed to get the platinum trophy for One Night Stand in around 45 minutes.
There are guides for One Night Stand out there, but essentially what you’re aiming to do is get all the available endings and fill out all the pictures on the phone that appears at the end of each route. The game gives you clues about how to get each picture, so you’re not flying totally blind.
From memory, there’s one other trophy which isn’t tied into an ending and relates to a decision that you have to make in the game, but it is kind of a spoiler, so I won’t say!
I would recommend anyone playing One Night Stand to play through a normal route first, and attempting to fill in the blanks themselves, but if you don’t want to do this then there are a lot of guides out there. This is the one I used, or you can find your own with a simple Google search – just make sure you add ‘game’ at the end of ‘One Night Stand’, or you could end up with some interesting search results!
Over at Playstationtrophies.org One Night Stand is rated with 1/10 difficulty and a 1-2 hour time estimate. I agree with the difficulty rating; nothing in this game is a challenge, and even without guides everything is quite straightforward and easily figured out. The 1-2 hours estimated platinum time is probably fair. Like I said, I got it in 45 minutes, but I used a guide for the most part, so without a guide 1-2 hours is pretty reasonable.
