So, I got the game for Christmas and I just tried it tonight on solo play. Basically, I woke up on an island, learned that I needed to try to find a boat, but then I got trench foot, slowing my movement. I died of hunger before I found the boat while two unknown monsters were following me. That is about all I want to say to avoid spoilers.
So, first of all, I like the game mechanics. Simple and easy to play with a nice combination of narrative and skillful planning involved. The game moved along at a nice quick pace.
For me, the game has decent replayability. For one, the game has 5 scenarios, each scenario gets a random map set up, random character(s) to use, and some limited randomization of the adventure/monster decks (my first scenario told me to use only one card out of 2-3 for three different numbers). For me, that is pretty good replayability. For example, I love the new Arkham Horror game, but it only comes with (I think) 4 scenarios. The maps are different for each scenario, but they are not random. If I don't see any problem with replayability with that game, then I certainly don't see any problem with the replayability with this game. Yes, both games are the most exciting the first couple of times you play a scenario, but they still have an appeal in that you can draw different cards, use different characters, and get a different narrative with each game, even if the overarching story is the same for each scenario. Also, there is the simple fact that there are very few board games that I own that I have actually played 4-5 times.
What about the idea of the game being unique? I really love this idea. Before I opened my game I really didn't know what I was going to get. In fact, I thought there was only island and desert terrain, so I was super excited to find that I had island and bayou. If I actually manage to play the game several times and feel hungry to relive the experience again, I can buy a new copy, with new terrain, new quests, new characters, and play the same game again but relive the experience of true discovery. I think that is pretty sweet. If I end up playing it only 2-3 times before moving on to another game (which is what I usually end up doing, as I have quite a collection to work my way through), then that is cool too. I also really like that if one of my friends have a copy, we can take turns playing each other's copy for new experiences. Some others on the forum have suggested trading games, which also sounds like a neat idea.
I just have one reservation. I have heard in other reviews that the game is fun during the exploration part, but falls apart later on when you are running around trying to accomplish tasks. In my first game, I died before I got that far, so I can't speak to that. But the idea of the nature of the game-changing halfway through is not necessarily a bad thing. I guess I will just have to play more and see.
Overall, seems like a fun game I can play with more casual players with a novel idea in that my copy is unique. It is not my favorite game (looking at you, Twilight Imperium!), but I think it was certainly worth the price of admission, and might even be worth the price of buying a second copy if I actually manage to exhaust the scenarios in my copy and I am still hungry for more.
