I mean of course not all games work! But for me personally literally every single game I wanted to play works! Everyone's experience is different. I mostly play single player games.
If you change it to single player you can see 81% of the top 1000 games are compatible and 90% of the top 100 are as well.
If you don't do single player its still around 76% for top 1000. Top 10 is 50%
Also just noticed that hitman 2 (Three isn't listed for some reason) does work!
