This is the first game I have worked on in babylonjs. I was impressed the new version supports modern typescript development and that is the main reason i chose it over other web technologies.
Myself and a few others are making an RPG game. We decided to use babylon to create the character equipment system while the rest of the app uses vue.js
We just put a babylon instance inside of a vue component, and it was pretty simple. Then we just position the main container with css. Its mostly a 2d game, but we wanted people to be able to customize their character in different ways. This character is from a unity asset store pack, which came with the source rig, and we exported it for babylonjs.
