Fame
If you're a top gamer or on a top team, you'll be considered a god among your kind. Nerds everywhere will be clamoring for a t-shirt with your picture on it. Fans will make pictures of you on crushed velvet poster board and you will have more Facebook friends than you can possibly handle.
Every Tweet that comes from your precious fingers will be retweeted and gawked over ad infinitum by wide-eyed middle school kids and awkward adults who might cosplay as you and make you nervous at gaming conventions when asking for pictures and autographs.
