Good deal? Tropico 4 Gold Edition for Steam - 75% off @ Nuuvem

wait for the complete edition

Winter sale, it was $10 (for both) on Steam as well.

If you read that site's ToS you have to agree that you reside in South America before registering, since that's the only region the publishers have authorized them to sell their games. That's not to say that the site is actually enforcing that, but I'd only try buying there as a last resort.

nice deal

I'd wait for a good deal on the complete collection, personally.
