It would be cool if they released some other katamari games on steam. Maybe katamari forever? I found out that game has some cool different gimmicks compared to the other games. But I've never played it myself.
Great game for Game Pass. I bought the first Katamari Damacy at its $20 budget launch price on a whim after seeing a short video of the concept and reading a review in a magazine (GameInformer?). Ended up being one of my favorite PS2 games and one of my most replayed games years later. Hopefully being included with Game Pass, it will encourage others to try it out and discover the series. It would be awesome if it generated enough interest to make a brand new Katamari game to be made with modern systems and controls in mind.
