I actually wasn't aware of that, that's helpful to know. Though I still think this idea would be very helpful. When you haven't written anything for a while are you really going to be checking comments regularly? It also increases motivation to leave a comment on an older game, since the author has a higher chance of seeing it. Though that point is a little moot with the fact there's a comments page, since if the author is active and still checks that page it'd be found anyway.
I just think that if someone goes through the time and effort to leave a review then it'd be nice to as an author be notified of thaT. I know I get a little rush of internet excitement when I get a pm notifcation or a comm notification, and I think that it's not only important to be able to know when a review is posted, but also it provides the same type of excitement those things do. I know when I check the storygame, or I guess comments now lol, I feel that excitement at a new review, so it'd just be nice to get that in notification forum.
And I don't believe it would be too hard to implement? I could be wrong, but there's a notification system already. There would just need to be a sensor for when a review is posted and notify the author of that storygame. Though it could be a lot harder than that, I'm not sure.
