Or maybe it's because only the slightly older players has enough intellect to write posts and discuss topics. Most of the younger teenagers and 10 year olds think nothing of writing or even trolling, they are too busy not using their heads.
I'm a few months away from a certain age, as for your average Crysis 2 age, I'm well below 30.
So everyone under 18 years is stupid? Because that is what you just wrote... Give me a break...
I did not speak such fallacy as to say "Everyone." Most, that is, Most people under 18 usually has better things(like doing nothing) than to write in forums.
To be honest I thought games like World of Warcraft would be the ones with the majority of advlt players.
