I just received this game the other day. I've played it several times on my own and in a two player game. It's a good quick dungeon crawl. Similar to Descent, but can be done much quicker. I also like the cooperative game play of Ravenloft. From what I can tell so far, luck of the cards and roll can make a HUGE difference, but that's common in many games.
Dominion is a great deck building game. It gives a lot of replay value with all of the different cards, and each game can be very different because of the card combos. It also has a good depth of strategy without being made overly complicated. Great game!
