I agree there were many others (beyond even these I can think of a several), but I think Ryan was mainly referring to was how many were regular online CTFs at the time.

Wasn't both barcode-shmarcode and oCTF both more in-person events than available online?

Sorry for the late reply, but you are correct, both events were in-person at the conferences!
