It will be interesting to see how they find the experience of using Electron/NW.JS to export a big project (Construct 3)
The obvious first choice for that is W10 universal apps.
We are a captive audience.
So the question is if they will try to get C3 on Steam.
I don't really see that as a necessity given that they already have a presence there with C2, and subscriptions don't fit into the Steam system that well(aside from iaps).
Plus there's all the issues they had with Steam as a distribution system. Slow updates, client requirement, etc.
