Heh that's an optimistic post Frogboy, hope it has an effect.
The difference in GC2 forums and even Sins forums from a game such as Demigod is the difference between what kind of player is attracted to Single Player games and who is attracted to multiplayer games. Multiplayer gaming and with it, competitive gaming seems to come hand in hand with quite a few behaviours that turn off the kind of people who play Sins/GC2 and of course who frequent them forums.
Competitive gaming seems to attract the following types of people:
1) People who think it's cool to be rude, these are kind of like your bullies at school, they attack to make themselves look like they know what they are talking about. It earns them 'respect' with some people because them weak individuals believe it decreases their chance of being attacked and being made to look the fool. Also others will side with them, they want to be on the side of the arrogant person, because they also like the idea of being one of these people that looks bigger than others.
2) People who like to stir up trouble, everyone who knows forums knows the type, they know how to cause multiple page long threads of people just arguing and name calling. They can even do it with the most obvious troll attempts, they just know how to hit people's buttons. They get off on the thought that they were the creators of it. Like there is some kind of positive for them to 'create' destruction.
3) Schadenfreudes/Sociopaths. People who like to "f*** people up!" in games. The gankers, the cheaters, the people who's ultimate enjoyment in an online game is the other person whining. They get enjoyment from the thought that the other person has just stopped enjoying what he is doing. They can be charismatic and influential but when it comes down to it they are quite antisocial. On forums they can appear like number 1 or number 2, in real life they are probably totally normal, give them anonymity and they will very likely turn on people for a reaction.
In real life all of them qualities are total negatives, frowned upon, would hinder careers if it was open, ruin your standing in society, with friends and partners. On the internet where anonymity gives these people a voice that has to be listened to, is invulnerable, and can even find plenty of support from like minded people, most of the normal people of the world will get drowned out amongst all the bile.
So what am I saying with this ridiculous rambling. You have a lot of fans, normal civilised people who frequent the GC2 forums who spilled over their good attitudes to Sins which is predominantly single player game. Even in the Sins community you have the unashamed rude and arrogant individuals but not many. Hopefully as Demigod has adopted a lot of these communities they will be a majority voice in this forum where you are going to attract a lot of all that is bad about multiplayer gamers, but I doubt it. I don't think it will be long before the forums are as bad as any PvP MMO forum, any FPS forum, or any RTS.
