Excellent empire-building game with a nicely narrative feel and lots of clever mechanics using the multi-talented Event cards. Basic version is excellent when there are space issues, and Deluxe is superb if you have a table to play on as well as the time to get all of the components together.
Events can sometimes be way too harsh, especially in the first Era. I think I had a case of beginners luck the first time I played, as I survived to Era 4. The next few games saw the destruction of my miniscule empire in Era 1, thanks to Attacks and Earthquakes.
For a print and play game, Pocket Civ is of especially high quality. Absolutely excels, and I would be more than happy to pay for a boxed version (solitaire empire building games are thin on the ground) - and the fact that this is available totally free is the icing on an already very appetising cake.
