When I watched that Playstation TV video, I felt that Jeff genuinely liked P4 with how he described the game to Dan, which was surprising given his general indifference to games like that and anime in general. I have no plans to watch the ER any time soon, but I am very curious to see how he came around liking that game.
Jeff always liked the series and actually bought P4 for himself but didn't have time for it so they did it for the site. But the game ended up being quite beloved by Jeff and Vinny because of the characters. Can't blame them cuz after I finished Golden, i'm now a huge fan of the game and series as well. I'm giving P3 another shot because of it and P4 actually did a better job teaching their gameplay mechanics than P3 did.
Gotta say that during the ER, lots of fun convos happened not only between Vinny and Jeff but there were also eps where Ryan and Dave joined in or made passing comments. It really brought me back to the early GB days. I think it's worth watching for all of that if you don't ever plan on playing the game.
