Interesting, but I couldn't get Rifts to show up anywhere so /fail.
I made it through to "Genre shouldn't matter" then "Not really" and got caught in a loop. (Eventually breaking out into GURPS). The way I cut my genres is by style of game, not by period - games like Dread, Wushu, and Dogs in the Vineyard are easy to port out of their default settings.I didn't make it past the first page - no historical roleplaying.
