The ethics of cybernetics and the boundaries of the human mind are themes that are explored in both franchises. Corporate or governmental conspiracies related to the usage of futuristic technologies are a major themes in both series. Cyberbrains (GitS) or data chip implants (Quantum), if you like a good mix of SF with action, you'll enjoy both series. Note that .hack is a much light-hearted version compared to Stand Alone Complex, which is for the more hardened viewers.
