6) Final approach
With the game beta development continually checking off more and more items on the to-do list I started focusing on the designated store: Valve's Steam.
Steam is the largest PC gaming store by far, so it was a fairly obvious choice. I did my research and it was a bit scary: integrating a game, especially with achievements, save files and leaderboards into Steam sounds like a tough challenge.
I took a deep breath and dove in.
Steam itself presents a metric ton of documents and explanations for game developers to help them through, but those were somehow missing key points. Perhaps they were obvious to expert developers, but I was left baffled.
Thankfully, the internet had the answers - from understanding the nooks and crannies of the Steam SDK to configuring game builds and all the other features.
Wasn't too long before solid builds were uploaded, features were tested, twicked and improved and the game took its final form on the Steam store.
