I understand the “writers block” but once you do have a vision or idea, it is incredibly hard to bring it into reality. Much like building a product you have to cut and cut and cut due to time/skill/money constraints. I think many people get hung up on “originality” part too much.

Most of the comments lamenting the idea stage come from those who have not pushed past that. Once you do have an idea, a vision, that is when the real work begins. It is also the most difficult. For every completed game no matter how bad, there is a graveyard of thousands of incomplete projects that no one sees. People vastly underestimate the effort it takes to make a complete game.

If you do struggle with, “what kind of game”, go play games. Alot of games. Write about the games. Between the likes and didnt likes, is the kind of game only you can make.
