I miss the 1Up stuff a lot too.
The one thing that 1Up had that pretty much no other podcast/show has been able to match is a balance of conflict/rivalry and friendship. They had a huge enough cast that there would be, usually, at least 3 people who had played the same game and they often had conflicting tastes therein.
These days, podcasts generally have everyone having similar tastes and/or the tastes are so divided that no one plays the same games. So one person will briefly describe a game and say "yeah, it's good" and everyone else will nod in complacent agreement or just stay in their lane.
Part of it is that the industry has spread out so much (there's too many games and too wide a breadth of things to cover) and there's no room for work forces the size of 1Up. Also, the tenor of the industry has changed, and conflict is often seen as being to "bro-y". Which I understand. I just wish there could be more critical conflict in analyzing games that doesn't come from one outlet vocally-subtweeting another outlet or critic in a passive aggressive way.
