it's GameJolt (now itch) and GOG for me instead of Steam, but apart from that ...
5 year ago the game was not basically a empty house with a lot of bugs, only a few guys working on it, experimenting with Unity. And even then I think it was worth it. There had been some big changes over time: new engine, full voice acting, new character designs, several interface redesigns/changes, minigames and since then at least 4 new characters, not countind Doja. The female player char is the next big step.
I don't think Office Party will take nearly as long. The team has already grown, they have more manpower now and more importantly experience.
