4P IRL. Plaza, Wandering Minstrel, Embassy, Journeyman in the kindgom... but no +buy. Played Smithy+BM and won. Yawn.
(Ok, fine, yes, I know. Don't even. Here, wait, let me go ahead and do it right now and save some space. The next reply will be "FTFY: 4P IRL, [strikethrough rest of message.] Just realize that not everyone hates 3-4P. First, I recommend using 16 Provinces in 4P to encourage engines with double-buy capacity [endorsed by Donald X here
http://forum.dominionstrategy.com/index.php?topic=15189.0.] Second, with an experienced playgroup, it's quite fast. Third, it's a different game with different strategic elements, and can be much less multi-solitaire-ish than 2P. Cursing isn't as automatic when taking the math into account that a player who ignores cursing to build gets an advantage over other players cursing each other. Figuring out if you should bother with Fool's Gold or other "win the split, win the game" cards in 4P is much trickier. Pins don't work. Counting points is harder. If anything, it's a more challenging variant than 2P. So enough hate.)
