I love when you don't say you're directing that post at me because, well...I'm not sure.
Visiting a message board is one thing. Spending hours upon hours of watching someone else play a video game? Ehhhh
I don't even think I could put up with a 5 hour baseball game, before someone tries to use the whole sports argument.
What you consider call of duty (casual) and what other people consider call of duty (competitive) are two completely different games. It's much more fun for someone who plays competitive to watch it because they can understand it and learn from it. I suppose it's like golf. I would imagine no one likes to watch golf unless they actually play it themselves.
