I’ve discovered another quick review of In Between, this one is quite a bit more favourable than the official Game Chef one, but also not as in depth. It's short, so I'm going to quote it entirely:
The Good: Stuck between worlds trying to atone for sins? I love the concept and I like how the bidding system works with the dice and your power pools. It gets harder the more you accomplish because you lose power.
The Bad: Dice, lots and lots of dice. You need at least 15d6 per person. If one theme this year is maps, the other one would be dice.
The Other: I love how striking the title page is. It’s simple black and white, but it really made me interested in the game.
Would I play it? Yes, several times because apparently like a cat I have nine lives.
Thanks to Jonathan for his quick thoughts. He has also gone through and done the rest of the 58 Game Chef entries. What a job! Check out his blog.
