What games save to the Steam Cloud?
Solution 1:
The full up-to-date list.
Things to note:
- All Valve games use the Steam cloud.
- The majority of games on that list are indie titles, not AAA games, probably because those titles were written specifically with Steam in mind. Still, there are quite a few AAA games there as well.
Solution 2:
You can easily figure out for a particular game on its Steam page, look under Game Details. If it says Steam Cloud, it'll have your data in the sky.
