I'm a bit bored at the moment so I've decided to use my massive brainpower(-160IQ) to make ideas to make Crysis more interesting for Australians and the other guys(New Zealanders).
First Idea: A Interclan
This would basically all the players who want to participate are given a number and then numbers for each team are randomly generated and teams are made. This would make the game more interesting because you'd have to learn to work with your arch enemy/lover/person you insulted when they were a noob.
Second Idea: Country Scrim.
Same as above except Aus VS NZ etc etc.
Third Idea: Training Sessions.
Players who excel in one area could give lessons to players who aren't so good. An example would be Aussie giving Charlie a spamming Lesson and then Charlie giving Aussie a lesson with the SCAR.
Feel free to add any ideas below, remember that women have facial hair too!
