It would also be a great addition to have a "replay value" field for our games, so that we can easily set which games could be nice to come back to later
I’ll do you one better, the planned functionality is to automatically sync achievements across Steam, Microsoft, and Sony systems using their services. I haven’t looked but it may be possible to take in achievements from GiantBomb too, which would provide an “official” way to add achievements to games that don’t expose any.
