I have released my PC RPG game Golden Fall to steam.
Upon release there was a release sale.
However, once the release sale stopped, the game stopped selling completely.
So is it the price? 5$ is too much and 3$ is just about right?
Maybe the trailer is lacking?

No idea I'm afraid, not my area of expertise/experience.
I don't know if you are aware but this is more of a tabletop RPG forum rather than computer game forum. I guess there are probably members who have interests in both who may have the relevant experience to answer your question. However you might find better response at a forum specifically for PC RPGs...
