The question of the silent tower really reflects a question I think CF has struggled with for a while as gaming has evolved. Gamers expectations have changed a lot since CF's original vision was changed. It is simply assumed, I think, that any rpg will have a comprehensive list of items, monsters, areas, etc freely available on websites.

The question is, do you want to try to maintain the isolation of information or not? If you do, I think you really need to approach it by establishing a system of user accounts and marketing hard for the sub-sub niche of gamers that want to play a solo, unshared information, roleplaying, pvp, text rpg. To some extent this could simply be a practical decision; Do you want to try hard for the kind of game you feel is best, knowing that there will be fewer players, or do you compromise in order to expand the user base?

That said, if you want to keep the information isolation idea afloat, then go for it, and keep ST the way it is. You like it better in its current incarnation and I think most everyone agrees it's more interesting that way. But if you're not going to make a serious effort to wind back the clock on gaming, then yeah, it's probably best to update ST to a form that is fun and fair in spite of information sharing.

The next question then is, would you be legitimizing information sharing by doing this? I think you would see people arguing "well it's fine to share it now because nep specifically changed it for that reason."

Personally, I would enjoy CF most either of two ways: with complete sharing or complete isolation. The current situation where I know that there's a lot of sharing going on but I don't really participate out of ethical obligation doesn't really thrill me. I think I actually would like complete isolation best, but since I don't think that's really possible I think it would be better to just open CF up considerably, and accept/allow people to fully share information the way they do for other rpgs.

P.S.
If you do change silent tower, you should put the original up on some sort of alternate-test server so I can explore the puzzle version just for fun.
