Hello everyone. Decided to make a game for steam, convert exe to windows desctop. after start applications and the resolution of the game got wrong and if you touch it will go in the left side. Interested in the question, those who have already published games on steam from BB, to download on steam? the entire folder which did BB or necessary to alter the format for the store.
Has your game been green lit yet? You need to signup for greenlight and get green lit before you can launch on Steam. I would worry more on getting some good screenshots and video trailer together before you worry about the format for the store. If your game has good presentation you will still be looking at a month or so in greenlight but if you don't get votes you could be looking at months.
