This is my take on it atleast.
I personally like to talk about things I that I?m interested in. I like Tsukihime, and I'll probably like Fate/Stay Night. But I don't think that they do well as forum topics. The problem is that these are Visual Novels, and very good ones at that.
Every time I go to forum and read a topic on FSN, I kind of cringe. I know that it's dangerous. See, the spoilers scare me.
For example, I was a good way through Tsukihime and I wanted to read people's takes on what was happening in Ciel's route. But by coming into the forums, I inadvertently stumbled across a major Kohaku spoiler. I'm talking about the big one, the one that would have blown me away. But instead of the climatic revelation and build up that the game would have presented me, I learned about it in a single sentence. With typos.
That was a disappointment. So I stopped reading the forums until I was done with the game. I took me months to finish, and by that time the forums had died down. The initial excitement was gone. I had played the game excessively because I felt that I had to finish it if I wanted to discuss it. Bad idea. By the time I was done, I had grown a little tired of Type Moon.
Now the same thing is happening with FSN. This is more the fault of me lurking Beast's Lair after Tsukihime, but I think it has made me less willing to post here. Reading around on the "other visual novel" has lead to me finding out who four of the servants are. Not in the sense of "Saber" or "Lancer" but in the sense of which heroes they are. Again, knowing this without even getting to know the characters first feels like it is robbing me of some of the experience. I also think I know what happens to Archer.
So this really explains two things. I want the game to come out because I keep learning more about it. This is mainly due to stuff like 4chan and Beast's Lair. The sooner it comes out the sooner I can play it and start ignoring the forums. But, see, that?s the problem. I don't want to discuss the game before hand, I don't want to talk about it while I play it, and by the time I have completed the massive novel everything has died down.
