I had a little paper with my game that says to go online to get more downloadable content i heard it will add more wonders to your game has anyone did this or heard about it?

Yup that's right. The site that it linked to to redeem it (2kgames.com/civredeem or something like that) will be updated in a few weeks time (I'll announce it in the forums so don't worry about checking the site daily).

As for what the DLC is, it's new Wonders and Relics, some are good some aren't. Can't find the list now, so you'll have to wait till I get home before I can provide you with the list.

Oh and just so you and everyone else knows, there will be 4 Downloadable packs, you get one fo them free depending on where you bought the pack (US only). The other three will obviously cost, but hopefully not much. They'll be released in a couple of weeks time. The latest patch added support for them.

Do you have an idea of what these packs will include (more nations, wonders, units)?

Here are the downloadable content details. Note the first was released today in the EU store.
