Sigil is not dead, it just smells funny.

Yet another WotC fumble. They're getting really good at it.

I don't want to believe all that effort was in vain. Maybe all the created software could be "recycled" for other type of project, for example a D&D wargame with a different system of rules, something like mixing Warhamer: Total War and the saga Heroes of Might & Magic. Lots of players would be "busy" playtesting their own homemade rules.
