I recently played Lost Valley for the second time. Unfortunately, I have to report that my earlier impression was correct. It's nicely produced and if you really like exploration games, you could get into it, but
it is rather mechanical and nothing exciting. None of the mechanics really combine in interesting ways. You just do it and there's not a lot of fun, strategy or tactics. It is beatifully produced though.
Goldbrau, on the other hand, was quite good despite playing with three (I hear it is better with four) and getting one rule wrong for 2/3 of the game. I expect with four and the correct rules it would be very good. It combines
elements I like (business game, simultaneous action selection) with some clever mechanics (the brewery/beergarden split, the boss mechanic) along with being generally well crafted. It is a little fiddly and isn't perfect, but
it's quite good.
