I like fun games. Games that let me go nuts and do all sorts of dumb shit are usually the most fun. The games that usually let me do the dumbest shit tend to be open world games, so I'm going to have to disagree with your call for some weird open world boycott.
It used to be that Jeff, Brad, or someone else would say "Heh, I should make a video of that." or, someone would say something and someone would chime in "Sounds like Premium Content!", and then we'd never hear about it again. Sometimes, something would sound like a cool idea, so people would keep bugging the guys about it to the point where they'd say "Well, now I just don't really want to do it, so drop it."
Then, there's Dan.
If Dan gets an idea in his head about something he wants to do...MOTHERFUCKER GETS IT DONE. Wants to ride a rollercoaster while playing Mario? Done. Wants to drag the guys through the nightmarish hellscape of Mario Party? Done. Wants to see Drew experience the entire Metal Gear series? Done.
Don't get upset or annoyed about Dan doing too much. Be upset or annoyed by the others not having his drive.
Ugh. Hiring a straight, white male. REAL bold, Kotaku!
Jokes aside, I wish Kleptok the best of luck in his future. I really don't go to Kotaku (Gawker stuff has bugged me for the last few years), and I doubt I'll start now, but they hired themselves a damn fine writer, and I hope they put him to good use!
There is no magic cure to people being assholes on the internet. Want to help? Don't be a dick. That's how you can do your part. As for this harassment stuff? It's not going away, unfortunately, until certain aspects of internet anonymity are changed.
