This free-to-play autobattler recently received an HD upgrade, which helped it gain enough attention to reach the top of SteamDB's 'Popular Releases' category.https://www.notebookcheck.net/Free-autobattler-tops-SteamDB-charts-following-HD-upgrade.963273.0.html
Do be aware this is not only an extremely monetized game, but those overwhelmingly good reviews are all one word or so with little playtime (i.e. bots). Heck the actual reviews, good and bad, mention the bots both in game and on the review, pumping up the rating.
