After reading these two thorough questions about rationales behind off and on topic ITG questions, I would still like to have a sanity check because the criterions I have in mind do not appear in them.
I would like to find a game (obviously) and do not have any video, audio or screenshot, but, I specifically know the os on which it was played, which happen to be a very unusual one for games, probably limiting the possibilities, as well as a pretty narrow time interval in which the game have been played.
Whould those be enough to ask a question about identifying a game, or should I continue banging my head at google's door?
