Unlike you internationalers, American football is the most popular sport around here. And soccer is the most dominant sport in the world, actually. Not all teams excel in every sport, though. I mean, Spain and Brazil are, in my opinion, the most dominant soccer teams in these current times.
Well, the games you mentioned are pretty much in the 'greatest hits' level, which I can understand. I'm not into FPS as well, but I'm more into side scrolling shooters (games that are 10x harder than Galaga, for example). It's ok to be casual, but sadly you may not get anything out of it. If you take it to the extreme, you just might get something big out of it.
