You just mansplained zip files and video games to a TECHNOLOGY JOURNALIST, VIDEO GAME REVIEWER, and VIDEO GAME DEVELOPER. I told you what happened. It wanted extra shit installed when I tried to run the exe that was in the zip that holds the info for the computer so that I can play the game.
I would suggest that you test your public builds on older machines and see what types of requirements and errors they kick up.
Given the kinds of games that you guys develop, and the sizes, a web build won't be viable for everyone. I don't know how big the web build of your 231 MB zipped download would be but there's no way any of my browsers would be able to handle it.
