Well yes, in the metaphorical, non-violent sense. I think it would behoove the community, to exercise the real power they have, their wallet. We love the series and I'm sure most of us have hundreds or thousands of hours tooling around a city or country side, wreaking all sorts of delightful mayhem. However, to get publishers to make changes to their business models, we as the consumer, can exercise our right to not purchase their products. I'm not talking about just online content, but all the content.
Did I love Red Dead Redemption? Gods yes! Am I looking forward to RDR2? With so much urgency! Will I buy it? No. I will not support a publisher that treats its passionate and loyal fan base like so much flotsam because a percentage of a percentage of that fan base cheats, hacks, and otherwise maliciously "games" the experience; either because they can or to simply ruin everyone's good time.
As a community, this is what we need to do. Negative reviews on steam is an excellent way to start. So is petition after petition. But none of that matters if the next product to come from this developer/publisher group makes a billion dollars in the first hour. We need to speak with our wallets. Not playing the games we own is useless. They have our money already, but if we can poison the well through negative reviews, public (but respectful and factual) denunciations of the publisher, that could have an impact on those gamers who are growing up and looking to purchase GTA.
There are so many videos on YouTube about GTA, that my oldest drools for the day when he will get to play and mod and embrace the sandbox. Or he did until I told him that he won't be able to do anything but what thr publisher will "let" him do. Now he is is far less interested. Business models exist because consumers maintain them. When consumers change their spending, the business model has to change, or it goes under. I don't want Take 2 or R* to fold, I just want them to listen to their base and respond according to their policies and the comments of their consumers. We don't want cheaters online, fix that, but let us have our Mario's driving DeLoreans under the legs of God Ulla, being chased by Harambe and the Hulk on a mini bike.
