Many of the other games in this series, get a lot of press, and rightly so as they are some of my favourite games, and highly rated on BGG as well. Having said that, this title is well worth considering.
With unique worker placement and power ups, special ability buildings and production buildings, and a lead-and-follow action mechanic, this is a euro with lots of interaction and clever play.
Even without the expansion, I highly recommend this game, but if you can find the expansion, it takes this game to a perfect 10.
