Right now you can follow any number of games and the updates would appear in your activity feed.
Would be nice if we could have an easy way to check updates of games we have on our wishlist without the actual need of following said games. Just like the one we have atm (Chronological), but with updates only from our wishlist and maybe have a way to go to our wishlisted games news directly from that feed. at the moment you have to go to the wishlist click every game individually and then navigate to the news section. This would allow us to keep the follow for games we are playing and the wishlisted one for future ones.
