Yeah...I kinda worried it would sell for that much. That's one of the few times where torrents would be beneficial...especially when it comes to playing a visual novel that is very good since there won't be a lot of people who will buy a game for that much (espeically with the "specials" that comes with it). The remake...is it going to be in English or is it going to be Japanese only? I don't feel like waiting for another fan translation to come out...assuming they would still be willing to re-translate it.
Another one that comes to mind (although it's debatable on whether it's even a visual novel) would be the English translation of Princess Maker 2...where the physical copies never actually made it to retail. It's actually a pretty good game if you can still find it.
For current games though...in all honestly, I don't have a problem supporting most games that have a "reasonable" price...no higher than $50 for me including shipping. The damn shipping charges really rub me the wrong way though...that's why I would prefer to get games digitally if possible like Manga Gamer goes. It's too bad I don't know a service that offers that for Japanese games as well as the ability to patch digital games with english patches. It isn't meant to sound like an excuse, but it would be so much more accessible to have a universal website to download visual novels that are both Japanese and English that can be patched with fan translation patches. Less wait, less money spent, and it's only just a click away if you need to reinstall it. I REALLY don't want to get into arguments when it comes to physical VS digital though.
For $40, Cross channel is worth it. I wouldn't go much higher than that though, especially if you factor in shipping charges. I like it more than most of my actually video games and I've read it through multiple times...though I do have to say that it isn't for everyone. But with torrents gone...you won't know unless you are willing to gamble a bit.
