I have enjoyed Football for a while -- good sport, fun to watch.

I REALLY got into Football a few years back when I hopped on the fantasy football bandwagon -- a lot of strategy (projections, history, weekly match up, e.g., do I start Tom Brady against Baltimore or RG3 against StL?), statistics, a random element (injuries, x-factor players breaking out, coaches benching people), etc. There is quite a bit of crossover between that and many other strategy games.
