I’m hoping we have a few people on here who have had their games published on steam so that I can get some feedback from you guys on when the best time to put it up for greenlight would be.
I currently have my game sitting in the Concepts Section (AKA: The corner of Steam everyone forgot).

It’s mostly ignored, and that’s completely expected. The concept section is completely dead, seriously. I was the “Top rated all week” for pretty much two weeks straight with a grand total of 5 votes. Most steam users don’t even realize the Concept section exists. 
Having said that, I will eventually be putting my game on the real Greenlight area, that will be it’s “time to shine” and time to really get some attention going. My plan was to post it once I have a workable alpha demo people can play around with, and I had a proper website with a forum people can use. But I was curious to get your opinions on Greenlight, is sooner-than-later better than waiting until the game is playable? How important is it to have a semi-completed product to show off? If I can show off the concepts of what the game WILL be in a very polished manner is that all I need?
Basically in a nutshell, I’m trying to figure out if my tactic should be to post it up now, and gain exposure/momentum slowly, or post it later and blow people’s socks off? Most of you guys have seen my game; do you think in it’s current state with maybe a well polished dev-diary video explaining what features exists and what will be in the future would be enough? Should I wait?
