He's looking at the release schedule and seeing this:

Reading it myself, It seems to be indicating that there will be a pair of free "thank-you" packs for people who buy the game.  This is keeping with Stardock's anti-piracy through added-value system.

Thank goodness.  I have absolutely no qualms about buying expansions, but I despise nickle-and-dime DLC for two reasons:

1) Expansions are usually well-rounded with content for everyone (mod tools are updated, maybe a new campaign, certainly new monsters, new multiplayer modes, etc).  You buy it and you get lots of new content to play with.  It's also easier to keep everyone on the same page.

2) Can you imagine how hard it would be to know if you could use a mod, when it would depend on which content packs you had (looking at you, Sims).

Plus, DLC packs just seem.... cheap  to me.  An expansion, I dig.  DLC content, it really feels like the developers built the game to milk the people who want to expand the game.

So thanks, Stardock. 

I will start a tree roots campaign (because a grass roots campaign can only go so high) to have at least one of the expansions give us floating cities, flying and tunneling abilities, and maybe even underground cities for mountains. There will be an official post when the game is released.

Well you know, failing that, you could always mod that stuff in
