Exporting your game to the Steam Platform

I would like to know this as well. DrWho did someone already messaged you or you figured it out?

There is an older thread about this, maybe you’ll find some answers there. I have no game on Steam yet.
Please login to see this link.
Steam has an own documentation about setting up a store page and registration for your product which will lively involve some paperwork.
For your app a normal windows build is technically Steam-ready as long as you don’t need achievements and cloud save. You probably know that there’s the free Steamworks extension in the Clickstore that can handle Steam interactions, don’t know how well it is maintained tho.
In case you wanna check if your game is compliant with the Steam overlay you can always manually add a build to your library and test.

Hi! I am no expert but I have 4 games and a soundtrack on Steam now and may be able to assist.

There's a lot of setup on the Steamworks side of things but as far as your exe goes you don't have to change anything to it specifically. They'll give you a link to download the Steamworks dev kit and in there is a folder called 'content' which is where your game actually goes. Then you have to set up a batch file that includes your game's official AppID number with valve and by running that your game gets uploaded to their servers.

In all honesty I found this entire thing to be very daunting and confusing the first time I tried figuring it out, even with their documentation (which many times didnt really answer my questions!) The good news is that you should have access to the Steamworks dev group by now and there are many people there who know what they're doing and will be able to help you more than the documentation will.

Basically there are two major sections for every game up there: The App stuff (game build, achievements and etc) and the Store stuff (trailers, screenshots, general description etc). They will give you a checklist which appears on the right side of the screen and is super helpful to see what still needs to be done before you can submit your game to valve for them to give you the ok to release it publically. Some advice I'll give you now is that the game assets are a big pain in the ass because they want maybe 15-20 versions of your main game image and the sizes vary wildly. So say they want a main capsule image which has to be 331 x 167 (I'm making these numbers up now) and resizing your image to these weird specs might make it look not as good as you'd like, so there's some thought you have to put into it because of course you don't want it to look crappy.

P.S: To echo what julian82 said the Steamworks object is incredible and very powerful. Setting up achievements and using this thing to unlock them has almost always worked 100% of the time for me, and the times it didn't it was my error. If you can add achievements I highly suggest you do. Many players will want to 100% their games and by keeping them playing it has an added bonus of pushing them out of that 2 hour window of getting a refund too.

Thanks for the answer. I'm still far away from finishing my game but you gave some good advice!

Excellent tut by DavidN Please login to see this link.

Steam has changed a bit since David Made this video but you should still be able to follow it to get your game(s) up and running

Thanks, it has crossed my mind to do that.
Not sure how many people would want that.

Quote from DrWho

You would be surprised man. I would buy it for sure!

I will consider doing this, but I would probably try to find out how much of an interest there would be for it first.

I don't want to take over this thread anymore so I'll discus it father in a new thread sometime

Like others have said, as long as your game can boot up and there are no immediate technical issues with the game, you can publish your game.
SteamPipe (the tool for uploading builds) is a bit confusing at first, but once you have it setup, you can easily upload builds.
For Steamworks features (achievements, etc.), you will need to use the Steamworks extension (Please login to see this link.).
Obviously, you might want to consider other features such as trading cards, Steam Cloud, and so on. Steam Cloud can be enabled automatically and requires little configuration.
