Hey sorry for late replies don’t check here much and was on vacation but thanks it was a lot of work for 4 people to do.
I’m not sure I have another list in me, as we are still keeping the current list updated (me and Cryon) are normally checking unlisted store pages as they pop up and scrolling through old store listings for some games to show play anywhere pretty frequently and sometimes a few times a day.
for one of the reasons I personally was advocating for the full play anywhere list is it gets a bit murky with just specific features such as cross buy like you mentioned focus home games, it would start requiring finding folks willing to slap money for tests I think just for play anywhere me and genghis each drop around 20 ish testing some titles we couldn’t find answers for to confirm if say achievements worked or saves.
Its a pretty complicated and messy system at times, it does seem Xbox is taking notice (hoping due to this list but no idea), if you are on discord hope into the play anywhere channel for Xbox era we are pretty frequently discussing titles and flaws we hope are fixed/corrected
Edit: for games with just cross save, from a random shot in the dark I would say it’s around 50-70 titles
And for ones that have cross buy but not save or achievements would guess another 40-50 titles
