Ever since Steam opened the floodgates and started allowing quite literally anyone to post their games onto the storefront it became incredibly difficult to discover new and interesting things. Case in point, I haven't impulse-bought a game on Steam for a couple of years now, even though this is something I used to do frequently during the Steam Sales of old. The reason for this is that its simply impossible to stumble upon a hidden gem on Steam these days, you pretty much have to know about it before hand.
Thankfully, it does appear that Valve is aware of this little problem given that they have just recently released the Steam Discovery Update 2.0. While the list of features isn't extremely long, you'll be glad to hear that the new storefront is now focused more on allowing you to personalize what types of games you're interested in, rather than simply spamming you with random nonsense based on a game you played eons ago.
But perhaps the most interesting change, to my interests anyway, is the addition of a "Recently Updated" section. This feature existed for quite a while now, but until recently it only showcased the last few games that got updated, regardless if you own or even care about them, rendering the whole system completely pointless. After the Discovery Update 2.0, however, the "Recently Updated" section now only contains patches for games that you either own or have previously wishlisted. It might not be a massive change, but its one that I could see bringing me back to games I've long since forgotten about, so it gets a thumbs up from me!
You can read more about the Discovery 2.0 Update over at the official announcement, but if you just want to give it a try for yourself and see what's different, you'll find that all of these changes are already live on Steam. And while you're there, I'd recommend you check out Momodora: Reverie Under the Moonlight - a Metroidvania action adventure that is far better than you might think on first glance.
