zendorf yes, as OddConfection said I had to greenlit it first.
jobel I cant say much about the process of getting the game onto steam because of contractual reasons, but its not a hard process. Theres a dev steam group and step-by-step tutorials that show up when youre greenlit.
I released my game as an early access title because I already had been seeling it as an alpha to make some money to keep working on it, so the earlier the buyers got their Steam keys, the better. Also this way I can study about how Steam works while I still work on the game, instead of having it finished then spending a good month learning about the whole process.
In any case, Im a single person working on this game. Im trying to get any money I can from it so I can keep working on it. I think that most other early access devs feel the same way. IMO its a lot better releasing something in alpha and getting money to keep working on it than cutting everything or making it episodic.
OddConfection Thanks! And thanks for the list!
