Well, you did ask. And I presume you’re only interested in my honest opinion. One of the things that always irritated me about IRC was people’s tendency to ignore you when you ask a question they can’t answer, so I’m going to just be frank here.
I would not buy any such product.
I cannot read them, rendering the only purpose in playing them, uh, obvious (and I’m not willing to pay for that alone). Probably they would not even work on my computer. My budget would not permit said expense even if I could fully understand the game in its entirety (with the possible exception of Synchronous Hearts), saying nothing of running it. And finally, playing the game would probably spoil things for me, and spoilers tend to SEVERELY negatively affect my enjoyment of games.
I’m willing to go out of my way to support Peach Princess (you’d probably know that Kumiko, at least more than random board readers), but not quite that far. I’m still a college student, after all.
