Microsoft's acquisition of Activision-Blizzard has been a story of ups and downs to some degree. We got Call of Duty in Xbox Game Pass, we've seen World of Warcraft begin to thrive again with greater creative freedom, and I have it on good authority that some very loved, dormant Activision-Blizzard IP are slated for a come back...more about that another time.

It's already on there isn't it? Spongebob Squarepants: Battle for Bikini Bottom Rehydrated was added back in early March. 

Director’s Take: Season 16 on the Horizon - News - Overwatch

That's the cover art for the Patrick solo game that came out not BFBB

Finished Atomfall and I really liked it, bit short (13 hours) but their were moments I did not want to stop playing and that's rare for me.

Wonder which those could be? ABK doesn't have that many dormant IP of significance. Guitar/DJ Hero, Spyro, Crash, Skylanders, Prototype, StarCraft. I do remember that Activision had sent out a marketing survey not too long before Xbox bought them asking if people would be interested in buying a Skylanders Remaster Collection that didn't require buying NFC figurines to play, but that seemed to just be a way to gauge interest, they didn't seem to have a studio actually working on it with so many of their studios on CoD assistance.
