A question recently was asked, Racing Game in Arcade where you can save your game. Based on the information the asker was able to provide, this was flagged as off-topic, as there was only criteria he provided from recollection.
I had an idea about the game the user might be referring to, but didn't want to add an answer, since I knew it was off-topic and would be put on hold/closed. I contemplated adding a comment with the game I had in mind to try to help the asker out and maybe point him in the right direction, but wasn't sure if that was appropriate either. Another user added a comment with a possible game, so I ended up adding mine as well.
My question, then... Was adding my comment with a possible solution appropriate for this off-topic question? I did want to help potentially point the asker in the right direction. But, on the other hand, I don't want that asker (or any others) to get the idea that even though they asked an off-topic question, they still got an answer via comments, so asking these types of questions again in the future (knowing they are off-topic) is fine.
