There is such a thing as a game being TOO balanced, and I think Alien Frontiers is it. The final few turns just seem too close, regardless of what has happened earlier in the game. The more I play it, the less impressed I am with it. Also, the Shipyard mechanic is just way too important in the game; if you roll no pairs for the first four turns, I truly believe you are screwed.
A blast from the past game that I played for the first time 26 years after it's creation. Not quite as old school as it first seems when you pull out the dice and Ral Partha figures. At first I though, "Oh great, Talisman reprise", but it's really not bad at all. There are dice, but in the end what really matters is positioning and speed. If I'd played it in 1985, I probably would have given it a 7.
I can't in good conscience give this game better than a 5 because it just isn't my style of game at all. In fact, if it weren't Discworld, and had a typical boring fantasy theme, I'd probably only give it a 4. Strictly as a game, it's better than Talisman, but not so much better I would get excited about it. Sort of a high rent neighbor to Talisman.
That being said, the art is great, the card quotations are funny, and my girls and I laughed like crazy while playing, especially every time the luggage ran over someone, so that's worth something.
