Though I LOVE Netrunner, buyers please keep in mind that Android: Netrunner has already been discontinued by Fantasy Flight Games. On top of that, these data packs are already out of rotation.
oraroTo follow up to this, though, there's now a community run effort to maintain the tournament scene, who have even developed and released brand new cards as an expansion. Project NISEI, if you're looking.
fifthswitchIf you're looking for non-local-play, you should also check out Jinteki dot Net if you're not aware of them. Digital community with medium-level rules implementation (Playing cards may automatically perform their effects, but you have to let the opponent know what subroutine you're breaking, etc).
ReutanOnly local play, but the issue I'm seeing with Project NISEI is that it appears to be EU based, so doesn't quite help me in SoCal. It is interested they've created an entirely new data pack.
fifthswitchThere's almost 100% chance that SoCal has a meta; the Stimhack Slack group could probably point you in the right direction, and places like DriveThroughCards will ship you their new set from what I believe is within the States.
