Yeah, maybe a third of them did I play elsewhere. But I consider this a signal on how good the commender already is. Don't think there is a good way for steam

Yeah, maybe a third of them did I play elsewhere. But I consider this a signal on how good the commender already is. Don't think there is a good way for steam to pick that up automatically without it being a privacy nightmare. An "I played that" button would be nice, help steam improve/validate recommendations and might even be used to advertise new content / sequels / etc.
