Welcome to the site
There has been some nice tournaments in the past months, most of them (or maybe all of them

) hosted by Romeo. Not saying that price pols and so forth are big as in Dota or LoL, but stil nice. Most of the best players sign in and a lot of games are casted. It's stil casual though, not real esport.
Back in the day there was Sunday Night Fights, hosted by Ami and a bunch of other guys (the ones that run this very site), but it seems to be dead long ago. Hope they surprise us with a good tourney soon.
