Well I could name drop all the various Internet personalities I follow/has followed which talk about games, and see whether they could work. So I did precisely that:
Extra Credits: I personally would love to right now, but they're successful in their own right. That they used to be hosted on the Escapist is both a positive(they now what the deal is) and a negative(they left for a reason).
Errant Signal: He started a Patreon not too long ago, and I suspect that the quality of his videos would dramatically drop if he had to do a video a week. Plus, he'd kind of enter Yahtzee's territory more than Jim's.
Mr bitTongue: His videos come out too seldom.
The GameOverthinker: putting aside that I think the quality of his videos/tone in his arguments are not what I appreciate, that would mean that Bob has 3 videos a week to produce. Even if he'd manage to do that with no problem, I don't think the Escapist at large would like to see three videos a week from one single person/viewpoint.
Lazy Game Reviews: Has a Patreon, and is more into retro PC titles, which I suspect is not something an up-to-date publication as Escapist would want.
ReviewTechUSA: ...honestly, he's probably my best option. He already does videos on a weekly-ish basis, and he does commentary on current news stories, so he's in the same niche as Jim Sterling. And his way of supporting himself is by adding "This video is brought to you by [product x], [marketing lingo about product x], link below in description" to his videos so I could easily see him removing that if Escapist would pay him.
PachAttack: Another "good" option. Mr. Pachter comes to the discussion from a perspective that's kind of unique, in that he's primarily a business man that happens to focus on games rather than a video game enthusiast that focusses on the business side/art side/whatever, so I was sad to see his show go away. From some tweets from him I see that he would have liked to continue. That being said, he was frequently factually wrong(at one point describing a turn based strategy game as if it were real time) and he can come across as a bit condescending, and I don't know if Escapist would like him.
TotalBiscuit: Possible, but I think he prefers to be independent. And if nothing else, he is capital S Successful. He did appear on the last Escapist expo though, and him and Jim has referred to each other in their videos so he "has the ties" so to speak.
SuperBunnyHop: the guy behind it has a day job, hence why his videos don't come out as frequently. If he were to quit that day job it's possible that he could do it. The question is if he would be willing to make such a commitment/if he thinks he could do one video a week of sufficient quality.
AlphaOmegaSin: does videos often, but I don't really follow him, and the few I've seen I haven't really been impressed with his insight.
