By default, there is a minimum required download. Any additional assets that are needed will be downloaded in the background by the client using our ‘Download on Demand’ system.
You should be able to select a full download from within the launcher and have it work for the playtest. Please keep in mind that this will increase the install size of the EVE dramatically, as we are not migrating assets over from your current Wine install.
As to ‘if it matters’ - that’s difficult to say. DoD is quite robust as a system and has been used in EVE for many years. If you don’t normally choose to download the entire client for some reason, then you probably won’t need to for this test.
A complete download is very useful for people on slow connections and would like to download overnight, or if they are traveling and bandwidth caps / costs may apply.
