Stronghold Games' Terraforming Mars Ares Expedition Card Game Collectors Edition is reduced from $72.19 to $48.94 (32% off). Best price ever according to CamelCamelCamel.
Ranked 205 overall on BGG and 135 in Strategy Games, this blending of the Terraforming Mars experience with the mechanics of Race for the Galaxy is comfortably playable in 60 minutes although, being mostly card-based, in my opinion it lacks the visual impact of the former. Nevertheless, almost all my gaming friends prefer this over the full-blown board game.
It is relatively easy to learn (and, if you've played both Terraforming Mars and Race for the Galaxy, you already know how to play), with the only rules concept I've ever found that causes confusion being recognising the difference between increasing production and receiving resources. I consider it a family-friendly game.
Already have and own the original with all expansions; any thoughts on whether this sufficiently different to warrant a purchase?
