Not_MatlockLucky_PierreWonder if TF2 can learn stuff from the gradual rise and rise of some of the older games that are now getting massive audiences.That's mostly because developers/publishers are learning that they can make big money from these tournaments.
Valve's got other things on their minds than comp TF2.
Because nintendo payed a single dollar to have smash at evo (oh wait, no, in fact they have never sponsered an american tournament)
