GamePassport: awesome site to see current PC Game Pass titles, with filters for genre, graphics, metascore, time to complete, and highlighting newly added and soon leaving games
Find the next game to play with GamePassport, a convenient browser for the Xbox Game Pass library. Compare critic and user scores, filter by categories and features.
I've been using this site for a while now and it's the best one I've found for discovering Game Pass titles. There are a lot of filters that are useful for PC gamers, so it's not just console-focused.
I'm not affiliated with the site in any way. Just an enthusiastic user.
