You can go to the SteamDB page for a game, click App Info on the left, then look for the “Detected Technologies”. This will usually tell you what they’re using if it’s not a custom engine. You can use the Augmented Steam or SteamDB browser extensions to get a direct link to the SteamDB page from a game’s store page.

Also, SteamDB has a page here with aggregate data of how much each detected engine is used across Steam. Unity currently accounts for over half of the games using known engines (snapshot).

Edit: For non-Steam games you could check out IGDB.com. It has crowd-sourced data on all video games, including which game engine was used.

Team Fortress 2 and Fall Guys have this quality as well. I wish more games would embrace the goofiness. It’s harder to take a match so seriously as to become toxic when the game isn’t even taking itself seriously.

Jake Kaufman always does amazing work, here’s some of my favorites of his from the Shantae series: https://youtu.be/ovk4ygEzMCI

Cave Story has some great retro tracks. Some people prefer the originals but I played it with the arranged versions: https://youtube.com/playlist?list=PLr5fTLogAd5tW_oPORRtgznxL-kUt9z7h
