Regular research in a game that is likely to last a couple hundred turns would make Bless strategies worthless. Besides, it would be nice if everyone had not already completed research in all paths midway through the game.

I am rooting for very difficult research. That way players will have to make strategic decisions about which pathways they want to research. If you don't employ very difficult research in a game as large as this one, when would you employ it?
