For those not in America, it is a (american) football nation. Though basketball is prob second but compared to (american) football where half the nation watches the superbowl (grandfinals) it cant even compare.
Chin up kid. You only have to wait a few years for DOTA. Wc3 was released in 2002 and Starcraft was released 98. The first AOS was on Starcraft so it will actually be even sooner. (AOS = Aeon of Strife the first as some would call MOBA)
