BioShock did a cooler campaign. Yours is primarily online, involving computer code and such. Ours involved riddles and real life events where you found bottles on beaches around the whole loving world, as well as purely promotional events.
My point is against this:

valve is very involved with their community ;)
BioShock developers put more work into theirs, at least in some ways. We loving win! Vox Populi!
