After hearing so many rave about it here on ENWorld, I saw
Adventurer and picked it up yesterday for $20. I can't say the game seems particularly good, though that's more because it doesn't seem like the kind of game I'd like, but the production qualities are absolutely terrible. The cards were unevenly cut, bad quality cardstock, grainy and sticky, thick and still flimsy, the printing process was uneven and the card backs go from normal to almost washed out in darkness. The box is oversized and flimsy (two things which don't go well together), there's a foam rubber dot in the center meant to keep the pack of cards from sliding around while in shrinkwrap which makes it really awkward to put stuff back in after they're unwrapped...
Stay away from the game. It's not worth $10 with production values like that, never mind $20.
I also picked up
We Didn't Playtest This At All for $8. That was a pleasant surprise. Only played it as a 2-player game, and it never went past the second turn, but this seems like a game meant for larger groups of people. Imagine an 8-player game of Fluxx that's guaranteed to end in 5 minutes. Little strategy, but should be a fun game, and has some really cool mechanics (e.g. a series of battle cards, where everyone does paper, rock, scissors, and then everyone who threw a particular sign loses). The object of the game is to win, and you win by either winning or being the last person who hasn't lost. Highly random, but fun, and a good price point and pretty decent quality. Great filler for waiting for others to arrive or finish up a game.
