Hello!
This is my first post, so I just wanted to begin to say that I am really excited for this project. I haven't had enough time to dig in yet. But I was just doing my morning browsing on the internet YouTube while my coffee was brewing, when I noticed a reviewer mention something about the DLC on the Steam Store.
Apparently the Steam Store Titles (meaning the little blue bars that you click on) display the Early access to Operation: Rolling Stone, Overlord and Michael, as "Early Access to Operation:xxx" and then follow with the cost.
This is misleading and gives the wrong impression. The description clearly indicates that it is when you donate you gain access. The problem is that you only learn that when you actually read the description. Anyone that is visiting the steam store will only see that, and will get the impression that you have paid for DLC. Which in itself isn't the worst thing, however it creates an impression that runs contrary to what the game product actually is and honestly it isn't accurate.
Now I am not familiar with what sort of policy or legal limitations you might be under with steam or anyone else, but if it is at all possible, I would edit the titles. Perhaps something along the lines of "Donate to EarlyAccess Operation: Overlord" or something along those lines.
Thank you for your time, and I am looking forward to seeing where this project goes, and even have a couple ideas about contributing myself.
