With the recent (very understandable) anger with Activision and their CEO Bobby Kotick over the company's seemingly callous and arrogant stance lately toward gamers, and even other companies, gamers are in the process of figuring out how to make their statement.
The obvious choice would be the boycott that is beginning to make headway. But such things are only as reliable as the honor of the person who agrees. Someone who is angry now, might not be as angry a few months from now when his buddies are playing Modern Warfare 2 or Guitar Hero 5 and he isn't.
For those who are angry but plan to play Activision's games anyway, it seems that their plan of attack is piracy. Below are some things to keep in mind if your plans include going this route, to quote:
All over the message boards of the gaming community, in private conversations, and the like, apparently this is the intent of many.
Activision is a business, and a business as its bottom line is to make as much profit as possible.
Part of making as much profit as possible obviously includes not enraging your customers to stand against you. And obviously Activision is currently losing their way a bit in that department. But they are not commiting any crimes.
You on the other hand, through piracy, would be commiting a crime. As a statement to the gaming industry that Gamers will not stand for what we see as undue price hikes, we would steal?
Instead of exploring the reasons for why people should buy the Activision games in question, explore the reasons why people shouldn't. Find the alternatives that will take the sting out of not playing and make them well known.
In short, reward the companies that are doing right by gamers by using your influence through word of mouth (invaluable in gaming) to inform others about.
Leaving (at least until they get their act together) companies like Activision to dwell in their imaginary world where they can treat people however they want and not expect due response.
