I like it a lot! We play at two and sometimes use a fan made variant that pre-populates some of spaces with a dummy color. This tightens up the game quite a bit. I love the way the game looks on the table and the tactility of the tiles. This is a game where the production elevates a good game into a great experience. I only wish that the cards were standard size for easier shuffling and handling.
I've been thinking about different ways we could draft at 2p. For example a Biblios style draft where each player draws 3 cards one at a time and has to keep one, give one to the opponent and place one into the bonus area. Or maybe just an open draft where we take turns picking from the current batch of face-up cards.
If anyone has the expansion I'd love to hear you experiences with that, especially at 2.
