First, lemme say I'm a long-time Stardock fan (starting with original GalCiv), and I only heard about this game on Sunday but I needed no other reason than that Stardock was putting it out to get me to pre-order it immediately.

That said, I have a few suggestions on future content.

1. We need a way to eliminate the fog of war within our borders.  Whether it's through a high-level spell (maybe level 10 or such), or through construction of destructable watchtowers outside of cities.  I don't want to have to build cities everywhere and then manage them just so I'm not surprised by a group of spiders attacking my capital.
2. We need a way to increase the per-city tile limit.  One way is to fix the "bug" that causes improvements (e.g. farms, mines, etc) to be counted as part of your 50-tile limit.  The other way would be to allow 10% tile limit increases as a high-level Civilization tech.  I like the latter better.  As an aside, you could allow us to keep building housing in a city and let the city continue to grow in population, even if there's no gain in city level beyond level 5.  (This would increase total civilization population, helping increase "epicness" of our civs).
3. We need a way to convert and/or create shards.  This could be through a high-level spell, and perhaps require huge resources.  But I'm playing on a small map and have only found 2 shards on it, and only 1 was anywhere near my civ (and my neighbor grabbed it first).  So I'm shardless, but I could save up resources to create one if that were a possibility.

Other than that, I'm excited for the coming patches and the future content I'm sure you guys have planned.  You always amaze me with your products, and learning about this one a few days ago was a really pleasant surprise.
