I have to say I'm very very impressed with Portal Games. I had ordered a mini expansion for Imperial Settlers from them and the very awesome t-shirt they sell called “Imperial Settler”. I just love that tee on so many levels. When they came up with this design it was a stroke of genius.
The mini expansion for Imperial Settlers makes passing in the game a tactical decision! It's going to be interesting to see how this impacts game play. Sometimes mini expansions can be just as hard hitting as larger expansions. And I think this along with the one I got below for another game fall into that category.
Although I haven't got the physical game of The Manhattan Project to the table yet (soon I'm sure), I have been playing the app version to get to grips with the game. Anyway there is a mini expansion for it called Nations that just arrived.
This expansion adds seven new cards to the game! These new cards are dealt out one to each player at the start of the game, and give a nationality and a unique ability to that player to use through out the game.
The cards will make the game even more thematic! Plus in the first full expansion they add even more nationalities apparently.
