yes it is worth. religious is an awesome tech tree on its own, i'dbe taking it occassionaly if there wasnt the talisman. A religious player is supposed to be realy difficult to take out - any defending ship you put out is always better than the rest, and its difficult to run intel on you, and your producing more and faster of everything. Religious tree does not need the talisman, or anything else. It stands pretty well along all other racial techs, its just a different Category of such.
