Thanks for voting eXpl0it3r!
Thankyou too Lo-X!
Yes, the amount of votes needed is kind of subjective. From what I've read on articles on this subject looks like you need to be on top X most voted games when Steam closes a batch of approved games. This X value could be top 100 or top 50. Recently they approved a group of 50 top voted games so it's something between 50 and 100.
What is nice to think is that when X games get greenlit, your entry moves X ranks forward.
More than one source that I read mentioned the "magic" number of upvotes being something around 10,000 with around 30,000 total votes for a "good" game which is also subjective. Anyway I'll let you guys know my numbers here and fellow SFML devs will get the game for free if they like it.
I understand that's a lot and the odds are against my game but I am happy just being there and close to declare my game finished on a "solid" state. I am on this project for more than 2 years now...
