Definitely not too late, as long as you enjoy it. If you are aiming to be top 1 in the world...then I don't know *shrugs*.

Well, you can still improve through playing a lot, right? Anyway, my point is "it is never late to join if you are there for the fun." If someone is happy and enjoy playing despite league status or whatever, then he can join late without any problem.

it is too late if u have family and multi billions business to take care with which all decisions depend on u, not to mention when u are too old and having some alzheimer's, parkinson's disease or some stuff like that i dont know whichever makes u forget strategies and make u cant micro correctly respectively :S

oh wait, too late as in too late to start starcraft2 when it has already been released for almost a year? my bad,lol
