Maybe I'm projecting or being overly sensitive, but when I see that I think that her goal is to change games I like to appeal more to other people. But... I like rescuing princesses. It's simple and easy, plus the structure of Mario and Zelda games has some far-reaching nostalgia. I like seeing gritty slums populated with thugs, hobos and hookers. I like knowing that, if I choose, I can push the button to kill NPCs. And while I didn't play the game, I thought it was hilarious that RDR had a trophy for tying a woman to the railroad tracks, something Sarkeesian specifically pointed out as troubling.
Sarkeesian's videos are inherently destructive criticism. She puts together a collage of things she views as problems. Which can put people who don't view them as problems on the defensive.
That's where I'm coming from, at least. The Jack Thompson comparison is apt in my view: how is it wrong in yours? (aside from the fact that JT tried to enforce his views legally, as has already been pointed out)
I like those games too. I don't see Anita's work as trying to destroy these games, I don't often agree with what she's saying or the context she puts some clips into, however I also think it's a good conversation to have since both the technology and audience have grow a lot since Mario saved Princess Peach for the first time.
Anita is presenting opinions for discussion. She's not saying that GTA shouldn't exist, just that the creators shouldn't rely on certain tropes over and over again. As someone who loves video games and has played a substantial amount, I agree that many games suffer from the same tired cliches. A significant amount of games use saving a female character (or for that matter killing one) in order to give the player motivation. As a gamer I want developers to do more than just use the same tired cliches over and over again in the same way I'm tired of some blockbuster movies using the same cliches endlessly.
Jack wanted it to be illegal for you to buy the games. He said that if you played them they taught you to kill. He didn't try to make videos exploring his opinion, he told you it was fact and lobbied against the industry.
There's a significant difference between the two.
