ruskul , I would even go as far as to say you have to be a registered Steamworks developer in order to gain right to use this 'Plugin' if it is made.
(So it would implement that you have signed NDA and your game (probably) has been greenlit).
This is 100% correct. A steamworks plugin would only be usable to Greenlit Games / Games sold through a publisher for sale on Steam. One would *need* access to the API calls tied directly to a steam approved game / app to have a functioning plugin.
That being said, having a functioning plugin steps up the presentation & quality of any Construct 2 game released on Steam and in turn makes C2 an even more of an easy choice when it comes to developing games for Mac/PC/Linux.
The question might come down to business though. Will enough people purchase / upgrade licenses for C2 to justify the development time required to implement greenworks into an official plugin..? I don't know. All i know is as soon as I get my first payout from steam, I already owe Scirra a chunk of that to upgrade to a business license. It's not much, but im sure there are a few others in a similar position, and many more yet to come.
