One major theme of Empires is VP tokens and well here is some of that. VP tokens appeared in Prosperity, originally just on Monument, but on Bishop and Goons too by the time the set was released. They haven't been used since because well you have to include the tokens. But we included the tokens so we were set. In fact there are three denominations of tokens this time: 1 VP, 2 VP, and 5 VP. The 2 VP ones are the same size as 1 VP but a different color; the 5 VP ones are bigger. That was what we could manage so that's what we did.

Groundskeeper is pretty basic; all VP cards you gain under her watch come with extra VP. That applies to both bought and otherwise gained cards, which can sometimes be exciting. They're cumulative; you can play a line of four Groundskeepers, buy an Estate and get +4 VP.
Temple is more exotic. The basic function of the card both gives you VP and puts VP on the pile - sitting right there on the Temples. And then someone buying a Temple takes that VP. So playing Temple is a VP now for you, and a VP later for someone, could be you or someone else. Temple has this weird word "Gathering" on the bottom, I should say something there. Well uh. It groups together a few cards that put VP on their piles, and lets another card refer to them (in a "let's not mess this up" way). So that's that.
Chariot Race is a funny one. You get a card (the one you reveal) and an Action no matter what; you also get +$1 and +1 VP if your card is costlier than theirs. Their card is the same all turn usually, so after the first Chariot Race you will know what your other Chariot Races are up against.
There was a lot you could do with VP tokens, and I did a lot with them. Nine of the kingdom card piles use them, and then there are all those Landmarks and Events. But those stories are for another day. Well more specifically, tomorrow and the next day, and then later when the Secret History goes up.
