The current notification sidebar is very short and list format gets quickly clogged up by streams of comment notifications. If you put how much activity has passed since you last saw a story on the games thumbnail itself it would improve readability and show you how much activity has passed on the games themselves. Allowing players to keep track of the games they are a part of more easily as notifications that fall off the edge of the sidebar on the homepage never reach me. See attached image for an example.
