I doubt it's anywhere near that simple. The EU, being a loose confederation of independent countries that had all been doing their own things for a very long time before joining up, has a wildly heterogeneous legal environment. Even in a single country like the US, whether a EULA will be considered enforceable depends heavily on a plethora of factors, including what court the case is being tried in.
