Heh - re: the new bishoujo game announcement thread, that's nuts all right. There are at least 15-20+ released a month!
The difficulty is that a thread isn't very well-suited to that sort of thing, because it'll get to be painful to track what has and what hasn't been posted. I think we may be better off having some sort of monthly index in the first few posts, and then announcements posts as things are added to the list. This seems like the sort of thing just more suited for a database than a thread!
In any case, we'll see what happens... I may at least be able to contribute the monthly listings out of Dengeki Hime or whatever.
