Tradition - the revision to the old tree is fantastic, and so front-loading free culture buildings is a nice medium buff. I'm on my second game, and the AI seem to sample from many trees, but do still finish some. Truly free GP from Wonders and policies - yes! GSEM counter - I like the approach of a modified count increase across all types. I have a more casual play style than most experienced players, and if I understand your approach, it would make it easier to go for a GE after a few GS, rather than seeming to have to wait until near the end game to spawn a GE after many, many GS. It would also reduce the delay for a first GS if you pop a GE from early wonders? Nice.
