Gave this a go with Limetime. Here's a recap:
Game 1 (Fountain, Tomb; Borrow; Peasant, Chancellor, Menagerie, Oasis, Tunnel, Moneylender, Giant, Stables, Farmland, Hireling)
We both went Moneylender/Peasant, and started trashing Copper for the points and the money. He went Menagerie earlier than me, loaded up on Stables, while I went heavy Peasant. I got to Teacher first with a plan to +Buy something and buy back my coppers for the Fountain points. His engine was clicking too fast, so I panicked and +Action'd Moneylender to try to trigger a big turn with Menagerie. It worked, but didn't help enough. Limetime dropped a +1 Action on Menagerie and it was all over. We both grabbed a few extra Tomb points with Farmland, but I didn't have the money Limetime had, and his mega-turn 18 finished me off.
Score was 36-24 w/o landmarks. Limetime had no copper. I had 6 but didn't get up to 10. I had a 15-11 edge in trashing, so Limetime won 47-39.
Game 2 (Battlefield, Wolf Den; Scouting Part, Inheritance; Vineyard, Native Village, Squire, Philosopher's Stone, Golem, Counterfeit, Giant, Graverobber, Native Village, Peddler)
Both opened Potion/Squire. Had to threaten early Vineyard buys. But that led to a happy truce, as we bought P Stones and Golems with the Potion. Extra squires helped Lime to an early Peddler inheritance. I got there a turn later, and grabbed a couple Estates to get the Battlefield edge. Won that 8-4 but had a lot of Wolf Den work to do. While I was buying my second Golem and P Stone, Limetime grabbed up 3 Vineyards.
Lime up 56-19, 57-21 after landmarks.
Game 3 (Keep; Forager, Scheme, Shanty Town, Trade Route, Advisor, Miser, Distant Lands, Merchant Guild, Outpost, Goons)
Lime used Advisor well, while Foraging away treasure to draw his deck by turn 14 or so. I would've resigned, but hey, Landmarks. I grabbed a few points and tried to hang on to my 15 from Keep. I did, but it just made 65-22 into 65-37.
Moral of the story: If you can build a good enough engine, it will still overpower something slower that gets even slower when fighting over Landmark points. Or maybe Limetime is just that much better than me (much more likely)!
