My favourite code of football is soccer or more correctly put, 'Association Football'. But I say that almost reluctantly because I also like the strategy of Gridiron and the "big game atmosphere" of the NFL. I think a lot of people identify with the vastness and wealth of the aforementioned, purely because it is simply mindboggling to consider. However, there are many great sports, of which not only are massive to followers of those codes but are just as popular. For example, Aussie Rules is huge in the southern states of Australia just to name one example of many. It's indeed a "world within a world" and on that note, I also think all sports have merits to play and follow.

I think my answers are reluctant because they are all great games. For example, Rugby League has often been described by its gurus as the "greatest game of all". While Rugby Union is a very intensive game indeed but often seen as played by the affluent, hence an exclusive sport although in reality, quite inclusive. How can I omit the rivalry of the ancient Irish Gaelic Football and Australia's own Aussie Rules Football? Which reminds me, the history of the game is quite remarkable - the many other forms the games took prior to their modern versions, such as a famous game Calcio Fiorentino played in Florence, Italy.

The aforementioned seem like the main codes (not counting kicking a tennis or cricket ball unexpectedly clearly against the rules of those sports, although in the case of the much softer to kick tennis ball, a party trick for the crowd). Yet, there are many other codes we don't necessarily think of in a big world of ball sports. These include wheelchair versions of the aforementioned, beach versions, masters versions, video game versions such as Pro Evolution Soccer to name a few, and some incredibly distorted versions, such as Penny Football, and that aside, a quite popular yet seemingly unorthodox mention is Canadian Football.
Of course, there are also indoor versions, with indoor soccer and Futsal being slightly different, despite seeming like the same thing to the untrained eye. It's a fairly global concept, despite the choices of my examples/links. If you can think of any forms I have forgotten to mention, by all means, list them above, as I ask about codes of football, and more to the point, what is your favourite code of football?
