Congrats to Shipwreck and the Mrs. I'm sure the show will take a nosedive when Cheapy and Wombat have to step up when Shipwreck is out and game-impaired.
Let's be honest, Cheapy's not going to make friends with neighbors in his building. He'll make Mrs. Cheapy do all of the work to make friends so that they have a place to drop off Tai in an emergency.
The Retronauts kickstarter page specifically mentions what the $12k was for:
We'd like to keep Retronauts operating at the same level of quality it's always had, but we unfortunately lack the resources necessary to make this dream a reality. As it stands, we need all of the proper equipment, an acoustically friendly space to record, and the many gadgets and gizmos that a regularly produced podcast demands. We've done our research, and selected modestly priced and durable gear that will assist in bringing you the same Retronauts you've listened to these many years. Okay, and maybe we'll pick up a few fancy, vibrating chairs if this thing breaks a million.
Since they've blown past the goal, now they're adding a lot of videos and other things to the Kickstarter to be worth the extra money. The physical goods also take up a good amount of the money, though they've been modest in design of the goals to limit how much they have to spend on that stuff.
