I think it would be nice being able to allow players to build maps without needing to recompile the whole game. This way you could as a developer just give the community access to your compiled editor (provided that would be legally possible). This would allow the community to create custom made maps and content and that are really easy to share. I also think sharing things through steam’s workshop would be awesome. User made maps and content is something I think will grow and could also really benefit both the community and the developers. I hope to see some of those features soon. This will also probably be on of the main features with valve’s new game engine.
