I'm interested on how they will be developing the suite since that's where the new apps are gonna be made. If it is really PWA, the apps can be made without using the suite since creating simple web apps can be done easily enough through online materials.
The suite should contain templates especially if it's going to be mainly games. Developers won't be encouraged in using the suite if it would just be the same as starting from scratch since they probably can do it on their own.
Yappadappadoo offers pre-configured components to be used by app developers.This will hasten the development process of PWAs, making it easier for them.Starting from scratch is just going to take their time.
