I just thought this might be relevant:

Basically they are changing the way that games get on steam. When Greenlight launches, the community will be the one to decide what games are sold on Steam with a vote system. Obviously this is mainly focused on Indie games.
Now my only concern is if this has any restrictions to what game engine is used, mainly if Construct 2 games could be accepted, via .exe wrapper for instance.
What do you think?
