[Captain Kwok]

You don't have to download the shipsets other players are using if you don't want to. The only difference is that their race will be replaced by one of the ones you already have each turn. So, the images used with that race will randomally switch between turns.

When downloading, it's best just to unzip the race to the default pictures\race directory. When using a mod, if the shipset is not found in the mod directory it will just look in the default directory.
