Ive found this site which has a seperate season mode of thier own, in which you can wager money on season games you play. I play $1.00 games regullary and have made some cash from it. If we can get the VG community on thier site they hold sponsered tournaments for decent cash prizes every once in a while! The website is www.umggaming.com, go check it out and have fun!
They would probably need to get a license from semc
Im not sure how it works i just know they have a set up over there.
