I think in any big event or competition like WCG a player should b allowed to play more than 1 game....
coz playing a single game does not pull out the potential inside a gamer... it takes hell lot a time... just to equilibriate with the LAN speed and the tension of the environment and other stuffs too....
What i've seen is, most of the time is being lost to start the first game - prob with settings, graphics, controls, etc. so.... in my point of view another 15 mins, after the 1st game is being played won't make much harm... since it wud b easier and fast to start the 2nd game after the 1st 1 being played successfully.....this way we may b able to expel the original gamer part inside all of us....
Last but not the least..... a single game may b won by total luck.... but its gonna take more than luck to win 2 consecutive luck supported game!
