I have been hearing a lot about the definition of a sport lately, and it's an interesting topic.
For anybody interested in going deeper into this topic, there are some very interesting discussions happening about this topic but applied to Starcraft 2 (thread is at
http://www.teamliquid.net/forum/view...pic_id=288621), and I guess e-sports in general. For anybody who doesn't know, the real times strategy game Starcraft 2 is a growing e-sport (electronic sport) that has many professional players and tournaments with $50,000+ prize pools.
Personally I think in the most literal sense of the term FRC is not a sport, rather it is a competition (along with Starcraft). But it's an incredibly complicated topic that would take a while to cover thoroughly (I wish I hadn't already done my Senior research paper ~-~)
